Electrical Safety

This equipment is categorized as a Class I device with Type BF or Type CF (ECG) applied parts.

Prevention of Electric Shock

In a hospital environment, dangerous electric current may occur as a result of the potential
difference between a contactable conductive part and connected equipment in treatment rooms.
The solution to the problem is consistent equipotential bonding. Medical equipment is connected
with connecting leads made up of sockets which are angled to the equipotential bonding
network in medical rooms.

[Figure 1.1 Equipotential Bonding]

Additional equipment connected to medical electrical equipment must comply with the pertinent
IEC standards (e.g. IEC 60950/EN 60950 for data processing equipment, IEC 60601-1/EN
60601-1 for medical devices). Furthermore, all components of the product shall comply with the
requirements for medical electrical systems IEC 60601-1-1/EN 60601-1-1. Any person
connecting additional equipment to the signal input and output ports of medical electrical
equipment must verify that the equipment complies with IEC 60601-1-1/EN 60601-1-1.

ECG-Related Information

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. The static shock, or ESD, is a discharge of the electrical energy
buildup from a charged individual to a lesser or uncharged individual or object. An ESD occurs
when an individual with an electrical energy build-up comes in to contact with conductive objects
such as metal doorknobs, file cabinets, computer equipment, and even other individuals.

Chapter 1 Safety 1 - 11

CAUTION

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

EMI

This product complies with EMI (Electromagnetic Interference) standards. However, using the
system inside an electromagnetic field can lower the quality of ultrasound images and even
damage the product.

If this occurs often, Samsung 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.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using the equation applicable to the frequency of the
transmitter, where p is the maximum output power rating of the transmitter in watts (W), according to
the transmitter’s manufacturer.

NOTE 1) At 80MHz and 800MHz, the separation distance for the higher frequency range applies.
NOTE 2) These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.

▐Avoiding Electromagnetic Interference

Typical interference on ultrasound imaging systems varies depending on electromagnetic
phenomena. Please refer to the following table:

A medical device can either generate or receive electromagnetic interference. The EMC
standards describe tests for both emitted and received interference.

Samsung Medison ultrasound systems do not generate interference in excess of the
referenced standards.

The Ultrasound System is designed to receive signals at radio frequency and is therefore

Chapter 1 Safety 1 - 19

susceptible to interference generated by RF energy sources. Examples of other sources of
interference are medical devices, information technology products, and radio and television
transmission towers. Tracing the source of radiated interference can be a difficult task.
Customers should consider the following in an attempt to locate the source:

- Is the interference intermittent or constant?

- Does the interference show up only with one transducer operating at the same

frequency or with several transducers?

- Do two different transducers operating at the same frequency have the same problem?

- Is the interference present if the system is moved to a different location in the facility?

The answers to these questions will help to determine if the problem resides with the
system or the scanning environment. After you answer this question, contact your local
Samsung Medison customer service representative.

Biological Safety

For safety instructions concerning probes and biopsies, refer to HS70A User Manual.

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
qualified personnel. No set of rules can be formulated that would be sufficiently complete to dictate the
correct response to 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.

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 its applications, have resulted in the need for increased and improved
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 supports the
ALARA principle.

Chapter 1 Safety 1 - 25

▐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, concentrate the 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 ALARA principle. The decision as to the amount
of acoustic output is, in the final 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 difficulty 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 biological effect is actually occurring, it 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 and 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 depending on your selection. Selecting the correct range of
acoustic intensity for the application is one of the first 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. Samsung Medison systems provide both
automatic and user-definable 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 output intensity. The output control allows you to select
intensity levels less than the defined maximum. Prudent use dictates that you select the lowest output
intensity consistent with good image quality.

▐Indirect Controls

The indirect controls are those that have an indirect effect on acoustic intensity. These controls affect

1 - 26 HS70A Service Manual

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 that is necessary in unscanned
mode.
Pulse repetition frequency or rate refers to the number of ultrasound bursts of energy over a specific
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.
The focus of the ultrasound beam affects the image resolution. To maintain or increase resolution at a
different focus requires a variation of 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, 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 an increased 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.

▐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-

Chapter 1 Safety 1 - 27

up, which ultimately increases the time. Diagnostic ultrasound is an important tool in medicine, and,
like any tool, should be used efficiently 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’s
default setting 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 the maximum output, based on the probe and
application, in increments of 0.1.

The application-specific nature of the default setting is also an important factor of index behavior. The
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 artificially high or low thermal index readings, e.g. the presence of
fluid or bone, or the flow 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 but do not rush the exam. Ensure that the indices are kept to a
minimum and that exposure time is limited without compromising diagnostic sensitivity.

 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 biological effects varies with peak pressure and ultrasound frequency. The MI

1 - 28 HS70A Service Manual

accounts for these two factors. The higher the MI value, the greater the likelihood of mechanical
bioeffects occurring. However, there is no specific MI value that means that a mechanical
bioeffect 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 occurring 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 specific body tissues. The actual amount of any temperature rise is
influenced by factors such as tissue type, vascularity, 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 fluid, 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 of, for example, cranial bone. The soft tissue
thermal index (TIs) informs the user about the potential for heating within soft homogeneous
tissue. TIc is displayed when you select a trans-cranial application.

You can select TI Display in Utility > Setup > Display > Display.

 Precision and Accuracy of Mechanical and Thermal Indices Displays

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 various range of probes and systems,
inherent acoustic output modeling errors, and measurement variation, 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 from 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.

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

Chapter 1 Safety 1 - 29

the measurement and calculation process. For example, the measured water tank values are
derated using a conservative, industry standard, attenuation coefficient 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.

A 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 a
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 variation. Variation among probes
and systems is a significant factor. Probe variability results from piezoelectric crystal efficiencies,
process-related impedance differences, and sensitive lens focusing parameter variations.
Differences in the system pulse voltage control and efficiencies 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, as well as variation 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 varying ranges of probes and systems,
inherent acoustic output modeling errors, and measurement variations. 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.

▐Control Effect - 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 on-screen output

1 - 30 HS70A Service Manual

values.

 Power

Power controls the system acoustic output. Two real-time output values are on the screen: a TI
and an 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 via software controls to keep the TI below the
system maximums. A decrease in pulse voltage will decrease the MI.

 Zoom

Increasing the zoom magnification may increase the frame rate. This action will increase the TI.
The number of focal zones may also increase automatically to improve resolution. This action
may change the 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 the MI.

 Focal no.

More focal zones may change both the TI and MI by changing the frame rate or focal depth
automatically. Lower frame rates decrease the TI. The 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.

▐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 as the primary mode and the TI change will be small.

 Color Sector Depth

Deeper color sector depth may automatically decrease color frame rate or change color focal zone
or color pulse length. The TI will change due to the combination of these effects. Generally, the TI

Chapter 1 Safety 1 - 31

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 and the 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 - 32 HS70A Service Manual

 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 the 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 the MI is 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.

 Probes

Each probe model available has unique specifications for contact area, beam shape, and center
frequency. Defaults are initialized when you select a probe. 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. Factory defaults vary with
probe, application, and mode. Defaults have been chosen below the FDA limits for intended

Chapter 1 Safety 1 - 33

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 (Bioeffect 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 28th January, 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).

▐In Situ, De-rated, 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 difficult to estimate the true In Situ intensity. An attenuation factor of 0.3 is used for general
reporting purposes. Therefore, the In Situvalue which is commonly reported uses the formula:

In Situ (derated) = Water

Since this value is not the true in situ intensity, the term “de-rated” 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. 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 of its shallowest
focal zones.

▐Acoustic Output and Measurement

The terms and symbols used in the acoustic output tables are defined 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, ([email protected]) may be

reported instead of MI (global maximum value) if ISPPA.3 is 190W/cm2.

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

pattern giving rise to the reported MI value.

WO 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 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

▐Acoustic Measurement Precision and Uncertainty

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

 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 of 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 first 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 reflecting) target suspension mechanisms.
Linearity of the balance system.
Extrapolation to the moment of switching the ultrasonic transducer (compensation for ringing and
thermal drift).

Chapter 1 Safety 1 - 37

Target imperfections.
Absorbing (reflecting ) target geometry and finite target size.
Target misalignment.
Ultrasonic transducer misalignment.
Water temperature.
Ultrasonic attenuation and acoustic streaming.
Coupling or shielding foil properties.
Plane-wave assumption.
Environmental influences.
Excitation voltage measurement.
Ultrasonic transducer temperature.

Effects due to nonlinear propagation and saturation loss.
The overall findings of the analysis give a rough Acoustic Power accuracy figure of ±10% for the frequency
range of 1 – 10 MHz.

▐Training

TIP

Principles of Operation of the Diagnostic Ultrasound System

Medical ultrasound images are created when the computer’s digital memory
converts the high-frequency wave signals that are transmitted and received by
the probe.

As ultrasound waves propagate through the human body, they generate
reflected signals whenever they encounter a change in density. For example,
reflected signals are generated when signals pass from fatty tissues to muscle
tissues. Reflected signals return to the probe where they are converted into
electronic signals. The reflected signals are amplified and processed by analog
and digital circuits that have filters for various frequencies and response time
options. Then they are again converted into high-frequency electronic signals,
and saved as a series of digital image signals. The monitor displays the image
signals stored on the storage device in real time.

The entire process of transmitting, receiving, and processing signals is
controlled by the computer.

information are also displayed.
