Operation Manual

Electrical Safety

This equipment has been veried as a Class I device with Type BF applied parts.

CAUTION:

As for US requirement, the LEAKAGE CURRENT might be measured from a center-tapped circuit



when the equipment connects in the United States to 240V supply system.

To help assure grounding reliability, connect to a “hospital grade” or “hospital only” grounded



power outlet.

Prevention of Electric Shock

In a hospital, dangerous currents are due to the potential differences between connected equipment
and touchable conducting parts found in medical rooms. The solution to the problem is consistent
equipotential bonding. Medical equipment is connected with connecting leads made up of angled
sockets to the equipotential bonding network in medical rooms.

Chapter 1 Safety

Additional equipment connected to medical electrical equipment must comply with the respective IEC

or ISO standards (e.g. IEC 60950 for data processing equipment). Furthermore all congurations shall

comply with the requirements for medical electrical systems (see IEC 60601-1-1 or clause 16 of the
3 Ed. of IEC 60601-1, respectively). Anybody connecting additional equipment to medical electrical

equipment congures a medical system and is therefore responsible that the system complies with the

requirements for medical electrical systems. Attention is drawn to the fact that local laws take priority
over the above-mentioned requirements. If in doubt, consult your local representative or the technical
service department.

WARNING:

Electric shock may exist result if this system, including and all of its externally mounted recording



and monitoring devices, is not properly grounded.

Do not remove the covers on the system; hazardous voltages are present inside. Cabinet panels



must be in place while the system is in use. All internal adjustments and replacements must be
made by a qualified MEDISON Customer Service Department.

Check the face, housing, and cable before use. Do not use and disconnect the power source, if



the face is cracked, chipped, or torn, the housing is damaged, or if the cable is abraded.

Always disconnect the system from the wall outlet prior to cleaning the system.



All patient contact devices, such as probes and ECG leads, must be removed from the patient



prior to application of a high voltage defibrillation pulse.

Never use the product in proximity to any flammable anesthetic gases (N2O) or oxidizing gases.



There is a risk of explosion.

Avoid places where the system is likely to be difficult to operate the disconnection device.



CAUTION:

The system has been designed for 100-120VAC and 200-240VAC; you should select the input



voltage of printer and VCR. Prior to connecting a peripheral power cord, verify that the voltage
indicated on the power cord matches the voltage rating of the peripheral device.

An isolation transformer protects the system from power surges. The isolation transformer



continues to operate when the system is in standby.

Do not immerse the cable in liquids. Cables are not waterproof.



The auxiliary socket outlets installed on this system are rated 100-120V and 200-240V with



maximum total load of 200W. Use these outlets only for supplying power to equipment that is
intended to be part of the ultrasound system. Do not connect additional multiple-socket outlets
or extension cords to the system.

Do not touch SIP/SOP and the patient simultaneously. There is a risk of electric shock from



leakage current.

Operation Manual

ECG-Related Information

WARNING:

This device is not intended to provide a primary ECG monitoring function, and therefore does



not have means of indicating an inoperative electrocardiograph.

Do not use ECG electrodes of HF surgical equipment. Any malfunctions in the HF surgical



equipment may result in burns to the patient.

Do not use ECG electrodes during cardiac pacemaker procedures or other electrical stimulators.



Do not use ECG leads and electrodes in an operating room.



ESD

Electrostatic discharge (ESD), commonly referred to as a static shock, is a naturally occurring
phenomenon. ESD is most prevalent during conditions of low humidity, which can be caused by
heating or air conditioning. During low humidity conditions, electrical charges naturally build up on
individuals, creating static electricity. An ESD occurs when an individual with an electrical energy

build-up comes in contact with conductive objects such as metal doorknobs, le cabinets, computer

equipment, and even other individuals. The static shock or ESD is a discharge of the electrical energy
build-up from a charged individual to a lesser or non-charged individual or object.

1-

10

CAUTION:

The level of electrical energy discharged from a system user or patient to an ultrasound system



can be significant enough to cause damage to the system or probes.

Always perform the pre-ESD preventive procedures before using connectors marked with the



ESD warning label.

Apply anti-static spray on carpets or linoleum.



−

Use anti-static mats.



−

Ground the product to the patient table or bed.



−

It is highly recommended that the user be given training on ESD-related warning symbols and



preventive procedures.

Chapter 1 Safety

EMI

Although this system has been manufactured in compliance with existing EMI (ElectroMagnetic

Interference) requirements, use of this system in the presence of an electromagnetic eld can cause

momentary degradation of the ultrasound image.

If this occurs often, MEDISON suggests a review of the environment in which the system is being
used, to identify possible sources of radiated emissions. These emissions could be from other
electrical devices used within the same room or an adjacent room. Communication devices such as
cellular phones and pagers can cause these emissions. The existence of radios, TVs, or microwave
transmission equipment nearby can also cause interference.

CAUTION: In cases where EMI is causing disturbances, it may be necessary to relocate this system.

EMC

The testing for EMC(Electromagnetic Compatibility) of this system has been performed according
to the international standard for EMC with medical devices (IEC60601-1-2). This IEC standard was
adopted in Europe as the European norm (EN60601-1-2).

ALARA Principle

Guidance for the use of diagnostic ultrasound is defined by the “as low as reasonably achievable”
(ALARA) principle. The decision as to what is reasonable has been left to the judgment and insight of

qualied personnel. No set of rules can be formulated that would be sufciently complete to dictate the

correct response for every circumstance. By keeping ultrasound exposure as low as possible, while
obtaining diagnostic images, users can minimize ultrasonic bioeffects.

Since the threshold for diagnostic ultrasound bioeffects is undetermined, it is the sonographer’s
responsibility to control the total energy transmitted into the patient. The sonographer must reconcile
exposure time with diagnostic image quality. To ensure diagnostic image quality and limit exposure
time, the ultrasound system provides controls that can be manipulated during the exam to optimize the
results of the exam.

The ability of the user to abide by the ALARA principle is important. Advances in diagnostic ultrasound
not only in the technology but also in the applications of the technology, have resulted in the need
for more and better information to guide the user. The output indices are designed to provide that
important information

There are a number of variables, which affect the way in which the output display indices can be used
to implement the ALARA principle. These variables include mass, body size, location of the bone
relative to the focal point, attenuation in the body, and ultrasound exposure time. Exposure time is an
especially useful variable, because the user controls it. The ability to limit the index values over time
support the ALARA principle.

Operation Manual

Applying ALARA

The system-imaging mode used depends upon the information needed. 2D-mode and M-mode
imaging provide anatomical information, while Doppler, Power, and Color imaging provide
information about blood flow. Scanned modes, like 2D-mode, Power, or Color, disperse or
scatter the ultrasonic energy over an area, while an unscanned mode, like M-mode or Doppler,
concentrates ultrasonic energy. Understanding the nature of the imaging mode being used allows
the sonographer to apply the ALARA principle with informed judgment. The probe frequency,
system set-up values, scanning techniques, and operator experience aid the sonographer in

meeting the denition of the ALARA principle.

The decision as to the amount of acoustic output is, in the nal analysis, up to the system operator.

This decision must be based on the following factors: type of patient, type of exam, patient history,

ease or difculty of obtaining diagnostically useful information, and the potential localized heating

of the patient due to probe surface temperatures. Prudent use of the system occurs when patient
exposure is limited to the lowest index reading for the shortest amount of time necessary to achieve
acceptable diagnostic results.

Although a high index reading does not mean that a bioeffect is actually occurring, a high index
reading should be taken seriously. Every effort should be made to reduce the possible effects of a
high index reading. Limiting exposure time is an effective way to accomplish this goal.

There are several system controls that the operator can use to adjust the image quality and limit
the acoustic intensity. These controls are related to the techniques that an operator might use
to implement ALARA. These controls can be divided into three categories: direct, indirect, and
receiver control.

Direct Controls

Application selection and the output intensity control directly affect acoustic intensity. There are
different ranges of allowable intensity or output based on your selection. Selecting the correct

range of acoustic intensity for the application is one of the rst things required during any exam. For

example, peripheral vascular intensity levels are not recommended for fetal exams. Some systems
automatically select the proper range for a particular procedure, while others require manual
selection. Ultimately, the user bears the responsibility for proper clinical use. The MEDISON system

provides both automatic and user-denable settings.

Output has direct impact on acoustic intensity. Once the application has been established, the
output control can be used to increase or decrease the intensity output. The output control allows

you to select intensity levels less than the dened maximum. Prudent use dictates that you select

the lowest output intensity consistent with good image quality.

1-

22

Chapter 1 Safety

Indirect Controls

The indirect controls are those that have an indirect effect on acoustic intensity. These controls
affect imaging mode, pulse repetition frequency, focus depth, pulse length, and probe selection.

The choice of imaging mode determines the nature of the ultrasound beam. 2D-mode is a scanning
mode, Doppler is a stationary or unscanned mode. A stationary ultrasound beam concentrates
energy on a single location. A moving or scanned ultrasound beam disperses the energy over a
wide area and the beam is only concentrated on a given area for a fraction of the time necessary in
unscanned mode.

Pulse repetition frequency or rate refers to the number of ultrasound bursts of energy over a

specic period of time. The higher the pulse repetition frequency, the more pulses of energy in a

given period of time. Several controls affect pulse repetition frequency: focal depth, display depth,
sample volume depth, color sensitivity, number of focal zones, and sector width controls.

Focus of the ultrasound beam affects the image resolution. To maintain or increase resolution
at a different focus requires a variation in output over the focal zone. This variation of output is a
function of system optimization. Different exams require different focal depths. Setting the focus to
the proper depth improves the resolution of the structure of interest.

Pulse length is the time during which the ultrasonic burst is turned on. The longer the pulse, the
greater the time-average intensity value. The greater the time-average intensity, the greater the
likelihood of temperature increase and cavitations. Pulse length or burst length or pulse duration is
the output pulse duration in pulsed Doppler. Increasing the Doppler sample volume increases the
pulse length.

Probe selection affects intensity indirectly. Tissue attenuation changes with frequency. The higher
the probe operating frequency, the greater the attenuation of the ultrasonic energy. Higher probe
operating frequencies require higher output intensity to scan at a deeper depth. To scan deeper at
the same output intensity, a lower probe frequency is required. Using more gain and output beyond
a point, without corresponding increases in image quality, can mean that a lower frequency probe
is needed.

■

Receiver Controls

Receiver controls are used by the operator to improve image quality. These controls have no
effect on output. Receiver controls only affect how the ultrasound echo is received. These
controls include gain, TGC, dynamic range, and image processing. The important thing to
remember, relative to output, is that receiver controls should be optimized before increasing
output. For example; before increasing output, optimize gain to improve image quality.

Operation Manual

Additional Considerations

Ensure that scanning time is kept to a minimum, and ensure that only medically required scanning
is performed. Never compromise quality by rushing through an exam. A poor exam will require
a follow-up, which ultimately increases the time. Diagnostic ultrasound is an important tool in

medicine, and, like any tool, should be used efciently and effectively.

Output Display Features

The system output display comprises two basic indices: a mechanical index and a thermal index.
The thermal index consists of the following indices: soft tissue (TIs), bone (TIb) and cranial bone
(TIc). One of these three thermal indices will be displayed at all times. Which one depends upon
the system preset or user choice, depending upon the application at hand.

The mechanical index is continuously displayed over the range of 0.0 to 1.9, in increments of 0.1.

The thermal index consists of the three indices, and only one of these is displayed at any one time.
Each probe application has a default selection that is appropriate for that combination. The TIb or
TIs is continuously displayed over the range of 0.0 to maximum output, based on the probe and
application, in increments of 0.1.

The application-specic nature of the default setting is also an important factor of index behavior.

A default setting is a system control state which is preset by the manufacturer or the operator.
The system has default index settings for the probe application. The default settings are invoked
automatically by the ultrasound system when power is turned on, new patient data is entered into
the system database, or a change in application takes place.

The decision as to which of the three thermal indices to display should be based on the following criteria:

Appropriate index for the application: TIs is used for imaging soft tissue; and TIb for a focus at or

near bone. Some factors might create articially high or low thermal index readings e.g. presence
of uid or bone, or the ow of blood. A highly attenuating tissue path, for example, will cause the

potential for local zone heating to be less than the thermal index displays.

Scanned modes versus unscanned modes of operation affect the thermal index. For scanned
modes, heating tends to be near the surface; for unscanned modes, the potential for heating tends
to be deeper in the focal zone.

Always limit ultrasound exposure time. Do not rush the exam. Ensure that the indices are kept to a

minimum and that exposure time is limited without compromising diagnostic sensitivity.

1-

24

Chapter 1 Safety

■

Mechanical Index (MI) Display

Mechanical bioeffects are threshold phenomena that occur when a certain level of output
is exceeded. The threshold level varies, however, with the type of tissue. The potential for
mechanical bioeffects varies with peak pressure and ultrasound frequency. The MI accounts for
these two factors. The higher the MI value, the greater the likelihood of mechanical bioeffects

occurring but there is no specic MI value that means that a mechanical effect will actually occur.

The MI should be used as a guide for implementing the ALARA principle.

■

Thermal Index (TI) Display

The TI informs the user about the potential for temperature increase occuring at the body surface,
within body tissue, or at the point of focus of the ultrasound beam on bone. The TI is an estimate

of the temperature increase in specic body tissues. The actual amount of any temperature rise
is inuenced by factors such as tissue type, vascularity, and mode of operation etc. The TI should

be used as a guide for implementing the ALARA principle.

The bone thermal index (TIb) informs the user about potential heating at or near the focus after

the ultrasound beam has passed through soft tissue or uid, for example, at or near second or

third trimester fetal bone.

The cranial bone thermal index (TIc) informs the user about the potential heating of bone at or
near the surface, for example, cranial bone.

The soft tissue thermal index (TIs) informs the user about the potential for heating within soft
homogeneous tissue.

You can select either TIs or TIb using the TIs/TIb selection on the Miscellaneous system setups.
TIc is displayed when you select a trans-cranial application.

■

Mechanical and Thermal indices Display Precision and Accuracy

The Mechanical and Thermal Indices on the system are precise to 0.1 units.

The MI and TI display accuracy estimates for the system are given in the Acoustic Output Tables
manual. These accuracy estimates are based on the variability range of probes and systems,
inherent acoustic output modeling errors and measurement variability, as described below.

The displayed values should be interpreted as relative information to help the system operator
achieve the ALARA principle through prudent use of the system. The values should not be
interpreted as actual physical values investigated tissue or organs. The initial data that is used
to support the output display is derived from laboratory measurements based on the AIUM
measurement standard. The measurements are then put into algorithms for calculating the
displayed output values.

1 -

25

Operation Manual

Many of the assumptions used in the process of measurement and calculation are conservative
in nature. Over-estimation of actual in situ exposure, for the vast majority of tissue paths, is built
into the measurement and calculation process. For example:

The measured water tank values are de-rated using a conservative, industry standard,

attenuation coefcient of 0.3dB/cm-MHz.

Conservative values for tissue characteristics were selected for use in the TI models.
Conservative values for tissue or bone absorption rates, blood perfusion rates, blood heat
capacity, and tissue thermal conductivity were selected.

Steady state temperature rise is assumed in the industry standard TI models, and the assumption is
made that the ultrasound probe is held steady in one position long enough for steady state to be reached.

A number of factors are considered when estimating the accuracy of display values: hardware
variations, algorithm accuracy estimation and measurement variability. Variability among probes

and systems is a signicant factor. Probe variability results from piezoelectric crystal efciencies,

process-related impedance differences, and sensitive lens focusing parameter variations.

Differences in the system pulse voltage control and efciencies are also a contributor to variability.

There are inherent uncertainties in the algorithms used for estimating acoustic output values over
the range of possible system operating conditions and pulse voltages. Inaccuracies in laboratory
measurements are related to differences in hydrophone calibration and performance, positioning,
alignment and digitization tolerances, and variability among test operators.

The conservative assumptions of the output estimation algorithms of linear propagation, at all
depths, through a 0.3dB/cm-MHz attenuated medium are not taken into account in calculation of
the accuracy estimate displayed. Neither linear propagation, nor uniform attenuation at the 0.3dB/
cm-MHz rate, occur in water tank measurements or in most tissue paths in the body. In the body,
different tissues and organs have dissimilar attenuation characteristics. In water, there is almost
no attenuation. In the body, and particularly in water tank measurements, non-linear propagation
and saturation losses occur as pulse voltages increase.

The display accuracy estimates take into account the variability ranges of probes and systems,
inherent acoustic output modeling errors, and measurement variability. Display accuracy
estimates are not based on errors in, or caused by measuring according to, the AIUM
measurement standards. They are also independent of the effects of non-linear loss on the
measured values.

Chapter 1 Safety

Control Effects - Control affecting the indices

As various system controls are adjusted, the TI and MI values may change. This will be most
apparent as the POWER control is adjusted; however, other system controls will affect the on­screen output values.

■

Power

Power controls the system acoustic output. Two real-time output values are on the screen: a TI
and a MI. They change as the system responds to POWER adjustments.
In combined modes, such as simultaneous Color, 2D-mode and pulsed Doppler, the individual
modes each add to the total TI. One mode will be the dominant contributor to this total. The
displayed MI will be from the mode with the largest peak pressure.

2D-mode Controls

■

2D-mode size

Narrowing the sector angle may increase the frame rate. This action will increase the TI. Pulse
voltage may be automatically adjusted down with software controls to keep the TI below the
system maximums. A decrease in pulse voltage will decrease MI.

■

Zoom

Increasing the zoom magnication may increase frame rate. This action will increase the TI. The

number of focal zones may also increase automatically to improve resolution. This action may
change MI since the peak intensity can occur at a different depth.

■

Persistence

A lower persistence will decrease the TI. Pulse voltage may be automatically increased. An
increase in pulse voltage will increase MI.

■

Focal no.

More focal zones may change both the TI and MI by changing frame rate or focal depth
automatically. Lower frame rates decrease the TI. MI displayed will correspond to the zone with
the largest peak intensity.

■

Focus

Changing the focal depth will change the MI. Generally, higher MI values will occur when the
focal depth is near the natural focus of the transducer.

27

Operation Manual

Color and Power Controls

■

Color Sensitivity

Increasing the color sensitivity may increase the TI. More time is spent scanning for color images.
Color pulses are the dominant pulse type in this mode.

■

Color Sector Width

Narrower color sector width will increase color frame rate and the TI will increase. The system
may automatically decrease pulse voltage to stay below the system maximum. A decrease in
pulse voltage will decrease the MI. If pulsed Doppler is also enabled then pulsed Doppler will
remain the dominant mode and the TI change will be small.

■

Color Sector Depth

Deeper color sector depth may automatically decrease color frame rate or select a new color
focal zone or color pulse length. The TI will change due to the combination of these effects.
Generally, the TI will decrease with increased color sector depth. MI will correspond to the peak
intensity of the dominant pulse type, which is a color pulse. However, if pulsed Doppler is also
enabled then pulsed Doppler will remain the dominant mode and the TI change will be small.

■

Scale

Using the SCALE control to increase the color velocity range may increase the TI. The system
will automatically adjust pulse voltage to stay below the system maximums. A decrease in pulse
voltage will also decrease MI.

■

Sec Width

A narrower 2D-mode sector width in Color imaging will increase color frame rate. The TI will
increase. MI will not change. If pulsed Doppler is also enabled, then pulsed Doppler will remain
as the primary mode and the TI change will be small.

M-mode and Doppler Controls

■

Speed

M-mode and Doppler sweep speed adjustments will not affect the MI. When M-mode sweep

speed changes, TI changes.

1-

28

Chapter 1 Safety

■

Simultaneous and Update Methods

Use of combination modes affects both the TI and MI through the combination of pulse types.
During simultaneous mode, the TI is additive. During auto-update and duplex, the TI will display
the dominant pulse type. The displayed MI will be from the mode with the largest peak pressure.

■

Sample Volume Depth

When Doppler sample volume depth is increased the Doppler PRF may automatically decrease.
A decrease in PRF will decrease the TI. The system may also automatically decrease the pulse
voltage to remain below the system maximum. A decrease in pulse voltage will decrease MI.

Doppler, CW, M-mode, and Color Imaging Controls

When a new imaging mode is selected, both the TI and the MI will change to default settings. Each
mode has a corresponding pulse repetition frequency and maximum intensity point. In combined
or simultaneous modes, the TI is the sum of the contribution from the modes enabled and MI is the
MI for the focal zone and mode with the largest derated intensity. If a mode is turned off and then
reselected, the system will return to the previously selected settings.

■

Probe

Each probe model available has unique specications for contact area, beam shape, and center

frequency. Defaults are initialized when you select a probe. MEDISON factory defaults vary with
probe, application, and selected mode. Defaults have been chosen below the FDA limits for
intended use.

■

Depth

An increase in 2D-mode depth will automatically decrease the 2D-mode frame rate. This would
decrease the TI. The system may also automatically choose a deeper 2D-mode focal depth. A
change of focal depth may change the MI. The MI displayed is that of the zone with the largest
peak intensity.

■

Application

Acoustic output defaults are set when you select an application. MEDISON factory defaults vary
with probe, application, and mode. Defaults have been chosen below the FDA limits for intended use

Acoustic Output and Measurement

Since the first usage of diagnostic ultrasound, the possible human biological effects (bioeffects)
of ultrasound exposure have been studied by various scientific and medical institutions. In
October 1987, the American Institute of Ultrasound in Medicine(AIUM) ratified a report prepared
by its Bioeffects Committee (Bioeffects Considerations for the Safety of Diagnostic Ultrasound, J
Ultrasound Med., Sept. 1988: Vol.7, No.9 Supplement), sometimes referred to as the Stowe Report,
which reviewed available data on possible effects of ultrasound exposure. Another report “Bioeffects
and Safety of Diagnostic Ultrasound,” dated January 28, 1993 provides more up to date information.

The acoustic output for this system has been measured and calculated in accordance with the
December 1985 “510(K) Guide for Measuring and Reporting Acoustic Output of Diagnostic
Ultrasound Medical Devices,” except that the hydrophone meets the requirements of “Acoustic
Output Measurement Standard for Diagnostic Ultrasound Equipment” (NEMA UD 2-1992)

Chapter 1 Safety

In Situ, Derated, and Water Value Intensities

All intensity parameters are measured in water. Since water does not absorb acoustic energy,
these water measurements represent a worst case value. Biological tissue does absorb acoustic
energy. The true value of the intensity at any point depends on the amount and type of tissue and
the frequency of the ultrasound that passes through the tissue. The intensity value in the tissue, In
Situ, has been estimated using the following formula:

In Situ = Water [

where: In Situ = In Situ Intensity Value

Water = Water Value Intensity

e = 2.7183

a = Attenuation Factor

Tissue a(dB/cm-MHz)

Brain .53

Heart .66

Kidney .79

Liver .43

Muscle .55

l = skin line to measurement depth (cm)

f = Center frequency of the transducer/system/mode combination(MHz)

Since the ultrasonic path during an examination is likely to pass through varying lengths and types

of tissue, it is difcult to estimate the true In Situ intensity. An attenuation factor of 0.3 is used

general reporting purpose; therefore, the In Situ value which is commonly reported uses the formula:

]

for

In Situ (derated) = Water [

Since this value is not the true In Situ intensity, the term “derated” is used.

The maximum derated and the maximum water values do not always occur at the same operating
condition; therefore, the reported maximum water and derated values may not be related to the In
Situ (derated) formula. Take for example a multi-zone array transducer that has maximum water
value intensities in its deepest zone: the same transducer may have its largest derated intensity in
one if its shallowest focal zones.

Acoustic Output and Measurement

The terms and symbols used in the acoustic output tables are dened in the following paragraphs.

ISPTA.3 The derated spatial-peak temporal-average intensity (milliwatts per square centimeter).

ISPPA.3 The derated spatial-peak pulse-average intensity (watts per square centimeter). The

value of IPA.3 at the position of global maximum MI (IPA.3@MI) may be reported
instead of ISPPA.3 if the global maximum MI is reported.

MI The Mechanical Index. The value of MI at the position of ISPPA.3, (MI@ISPPA.3) may

be reported instead of MI (global maximum value) if ISPPA.3 is 190W/cm

2

Pr.3 The derated peak rarefactional pressure (megapascals) associated with the transmit

pattern giving rise to the reported MI value.

WO The ultrasonic power (milliwatts). For the operating condition giving rise to ISPTA.3,

WO is the total time-average power;. For operating conditions subject to reporting
under ISPPA.3, WO is the ultrasonic power associated with the transmit pattern giving
rise to the value reported under ISPPA.3

Fc The center frequency (MHz). For MI and ISPPA.3, Fc is the center frequency

associated with the transmit pattern giving rise to the global maximum value of the
respective parameter. For ISPTA.3, for combined modes involving beam types of

unequal center frequency, Fc is dened as the overall ranges of center frequencies of

the respective transmit patterns.

ZSP The axial distance at which the reported parameter is measured (centimeters).

x-6,y-6 are respectively the in-plane (azimuth) and out-of-plane (elevation) -6 dimensions in the

x-y plane where ZSP is found (centimeters).

PD The pulse duration (microseconds) associated with the transmit pattern giving rise to

the reported value of the respective parameter.

PRF The pulse repetition frequency (Hz) associated with the transmit pattern giving rise to

the reported value of the respective parameter.

EBD The entrance beam dimensions for the azimuth and elevation planes (centimeters).

EDS The entrance dimensions of the scan for the azimuth and elevation planes (centimeters).

Acoustic Measurement Precision and Uncertainty

The Acoustic Measurement Precision and Acoustic Measurement Uncertainty are described below.

Quantity Precision Total Uncertainty

PII.3 (derated pulse intensity integral) 3.2 % +21 % to - 24 %

Wo (acoustic power) 6.2 % +/- 19 %

Pr.3 (derated rarefaction pressure) 5.4 % +/- 15 %

Fc (center frequency) < 1 % +/- 4.5 %

■

Systematic Uncertainties.

For the pulse intensity integral, derated rarefaction pressure Pr.3, center frequency and pulse
duration, the analysis includes considerations of the effects on accuracy of:
Hydrophone calibration drift or errors.

Hydrophone / Amp frequency response.

Spatial averaging.

Alignment errors.

Voltage measurement accuracy, including.

▶

Oscilloscope vertical accuracy.

▶

Oscilloscope offset accuracy.

▶

Oscilloscope clock accuracy.

▶

Oscilloscope Digitization rates.

▶

Noise.

The systematic uncertainties Acoustic power measurements using a Radiation Force are
measured through the use of calibrated NIST acoustic power sources.

We also refer to a September 1993 analysis done by a working group of the IEC technical

committee 87 and prepared by K. Beissner, as a rst supplement to IEC publication 1161.

The document includes analysis and discussion of the sources of error / measurement effects due to:

Balance system calibration.

Absorbing (or reecting) target suspension mechanisms.

Linearity of the balance system.

Extrapolation to the moment of switching the ultrasonic transducer (compensation for ringing and
thermal drift).

Target imperfections.

Absorbing (reecting) target geometry and nite target size.

Target misalignment.

The overall ndings of the analysis give a rough Acoustic Power accuracy gure of +/- 10% for

the frequency range of 1 - 10 MHz.

Diagnosis Mode Type

This product supports a variety of diagnosis modes including Basic Mode, Combined Mode, and Multi­Image Mode.

■

Basic Mode: Consists of different modes, each of which has a specic usage and function. By

default, 2D Mode is applied together with other mode.

■

Combined Mode: For an image, two or three Basic Modes are applied at the same time. By

default, 2D Mode is applied together with other mode. An image is viewed in a single screen.

■

Multi-Image Mode: The screen is divided into two (dual) or four (quad) sub screens, each of

which is used to view an image. Since each sub screen can display a different image, it can
be a very useful feature, allowing multilateral views of an organ.
