NOTE

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.

For information on User Key Setup, please refer to 'Chapter 3.
Utilities'.

The Control Panel

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

build-up 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.

■ 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.

CAUTION

- Apply anti-static spray to carpets or linoleum.

A medical device can either generate or receive electromagnetic interference. The EMC

standards describe tests for both emitted and received interference.

Samsung Medison’s ultrasound systems do not generate electromagnetic interference in

excess of the referenced standards.

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

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.

Users 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 probe operating at the same frequency or

with several probes?

- Do two different probes 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 the questions, contact your local

Samsung Medison customer service department.

ALARA Principle

Performing diagnoses using an ultrasound device is defined by the “As Low As Reasonably

Achievable” (ALARA) principle. The decision as to what is reasonable has been considered and

defined by many people. However, no set of rules can be formulated that would be sufficiently

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 user's knowledge of, and the ability to abide by, the ALARA principle is very 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. This

important information is based on a variety of ultrasound output data, and plays an important

2 - 24 WS80A Service Manual

role in putting the ALARA principle into effect.

Numerous variables affect the output data that forms the basis of the provided information.

These variables include mass, body size, location of the bone relative to the focal point,

attenuation in the body, and ultrasound exposure time. Among these, exposure time is the

variable that one must pay the most attention to. For, unlike other variables, exposure time is

entirely controlled by the operator of the ultrasound system.

▌ 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 unscanned modes like M-mode

or Doppler concentrate 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 definition of 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 necessarily mean that a bioeffect is occurring, it

should still 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 controls.

▌ 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

Chapter 2. Safety 2 - 25

correct range of acoustic intensity for the application is one of the priorities 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's systems provide both automatic and user-definable settings.

Output has a 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 lower than the defined maximum. Prudent use ensures

good image quality while employing the lowest output intensity.

▌ Indirect Controls

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

controls affect the 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

scanned 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.

The 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. Maintaining or increasing the

resolution at a different focal zone involves the adjustment of numerous outputs from the focal

zone. This output adjustment is one of the system’s optimization features. 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 cavitation. Pulse length, burst length, and

pulse duration refer to the output pulse duration in pulsed Doppler mode. In addition,

increasing the Doppler sample volume increases the pulse length.

2 - 26 WS80A Service Manual

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 greater 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 concerning output is that the receiver controls should be

optimized before increasing it. For example; before increasing output, gain should be

optimized 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 an exam. A poor exam will

require a follow-up, which ultimately increases the scanning 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. One of

the indices will be displayed according to the application currently in use, depending on the

system settings or user choice.

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 all

the time. Each probe application has an appropriate default selection for the 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.

Chapter 2. Safety 2 - 27

The application-specific nature of the default setting is also an important factor of index

behavior. The default setting is the 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 applied automatically by the ultrasound system when the power is turned on,

new patient data is entered into the system database, or a change of application takes place.

The decision as to which of the three thermal indices is displayed is 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 a bone. Elements such as fluid, bone, and blood flow may act as artifacts that

increase or decrease the TI. A highly attenuating tissue path, for example, may cause the

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

In comparison with the probe mode, unscanned modes of operation also affects 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.

 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 specific MI value that

means that a mechanical effect will definitely occur. The MI should only be used as a

guide for implementing the ALARA principle.

 Thermal Index (TI) Display

The TI informs the user of 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,

and mode of operation. The TI should be used only as a guide for implementing the

2 - 28 WS80A Service Manual

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, such as the

skeletal structure of a 2-3 month old fetus. The cranial bone thermal index (TIc) informs

the user about the potential heating of bone at or near the surface, for example, the

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 transcranial

application.

You can select the TI to display at Setup > Imaging > Display.

 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 section of this operation manual. These accuracy estimates are based on

the variability ranges of probes and systems, inherent acoustic output modeling errors,

and the 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 of 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 to calculate 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 is built into the

measurement and calculation process for the vast majority of tissue paths. For example,

the acoustic output values measured underwater are de-rated 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.

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

Chapter 2. Safety 2 - 29

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, measurement variability, and

variability among probes and systems are significant factors. Probe deviation results

from piezoelectric crystal efficiencies, process-related impedance differences, and

sensitive lens focusing parameter variations. Differences in the system pulse voltage

control and efficiencies also contribute to variability. There are inherent uncertainties in

the algorithms used to estimate 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

the calculation of the accuracy estimate displayed. Neither linear propagation nor

uniform attenuation at the 0.3dB/cm-MHz rate occurs in underwater 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 underwater 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 measured according to AIUM measurement standards but not

based on errors caused during the measurement. They are also independent of the

effects of non-linear loss on the measured values.

2 - 30 WS80A Service Manual

▌ Control Effect- Controls 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 also

affect the on-screen output values.

 Power

The power controls the system’s 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. Each mode is a vital 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 will increase the TI. The

pulse voltage may be automatically adjusted down by the software controls to keep the

TI below the system maximum. A decrease in pulse voltage will decrease MI.

 Zoom

Magnifying the image increases frame rate. This will also increase the TI. The number

of focal zones may automatically increase to enhance the resolution. In such

circumstances, the maximum intensity may occur at a different depth, which may

change the MI.

 Persistence

A lower persistence will decrease the TI. Pulse voltage may be automatically increased.

An increase in pulse voltage will increase MI.

 Focal no.

Increasing the number of 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 focal 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 increases the TI and the time spent to scan color images.

Color pulses are the dominant pulse type in this mode.

 Color Sector Width

Narrower color sector width will increase the color frame rate, and so the TI will increase.

Chapter 2. Safety 2 - 31

The system may automatically decrease the 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 the color frame rate, or select a

new color focal zone or color pulse length. The TI will change because of the combination

of these effects. Generally, the TI will decrease with the increased color sector depth. The

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 the pulse voltage to stay below the system maximum. A

decrease in pulse voltage will also decrease the MI.

2 - 32 WS80A Service Manual

 Sec Width

A narrower 2D-mode sector width in Color imaging will increase the color frame rate.

The TI will increase. 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.

 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 an additive element. 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 the Doppler sample volume depth is increased, the Doppler PRF may

automatically decrease. A decrease in PRF will decrease the TI. The system may also

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 revert to their 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 the value for the focal zone of the mode with the largest de-rated 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 the contact area, beam shape,

and center frequency. Settings are reset when you select a probe. Samsung Medison's

Chapter 2. Safety 2 - 33

factory defaults vary with probe, application and mode. Defaults that are below the FDA

limits have been chosen for intended use.

 Depth

An increase in the 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. Samsung Medison's

factory defaults vary with probe, application, and mode. Defaults that are below the

FDA limits have been chosen for intended use.

▌ Acoustic Output and Measurement

Since the first use 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 for the hydrophone, which 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 the largest possible value. Biological tissue absorbs

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:

)23.0( alf



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

e

Chapter 2. Safety 2 - 35

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. A de-rating factor of 0.3 is
used for general reporting purposes; therefore, the In Situ value which is commonly reported

uses the formula:

In Situ (derated) = Water

e

)069.0( lf



Since this value is not the true in situ intensity, the term “de-rated” is used.

The maximum de-rated and maximum water values do not always occur under the same

operating conditions. Therefore, the reported maximum water and de-rated values may not be

related to the In Situ (de-rated) formula. For example, a multi-zone array transducer has the

greatest water value intensities in its deepest zone. The same transducer may have its largest de-

rated 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 spartial-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

The derated peak rarefactional pressure (megapascals) associated with the transmit pattern

giving rise to the reported Pr.3 MI value.

WO Ultrasonic power(milliwatts). For operating conditions 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 frequency, Fc is defined as the overall ranges of center

frequencies of the respective transmit patterns.
