21 Acoustic Output

This section of the operation manual applies to the overall system including the main

unit, transducers, accessories and peripherals. This section contains important safety

information for operators of the device, pertaining to acoustic output and how to control

patient exposure through use of the ALARA (as low as reasonably achievable) principle.

Also this section contains information regarding the acoustic output testing and the

real-time output display.

Read this information carefully before using the system.

21.1 Concerns with Bioeffects

Diagnostic ultrasound is recognized as being safe. In fact, there have been no reports of

injuries to patients caused by diagnostic ultrasound.

It cannot be stated categorically that ultrasound is 100% safe. Studies have revealed

that ultrasound with extremely high intensity is harmful to body tissues.

Diagnostic ultrasound technology has made a great leap forward during the last several

years. This rapid advance has generated concerns about the potential risk of bioeffects

when new applications or diagnostic technologies become available.

21.2 Prudent Use Statement

Although there are no confirmed biological effects on patients caused by exposures

from present diagnostic ultrasound instruments, the possibility exists that such biological

effects may be identified in the future. Thus ultrasound should be used in a prudent

manner to provide medical benefit to the patient. High exposure levels and long

exposure times should be avoided while acquiring necessary clinical information.



Acoustic Output

21-2

21.3 ALARA Principle (As Low As Reasonably

Achievable)

It is required to practice ALARA when using ultrasound energy. Practicing ALARA

ensures that the total energy level is controlled below a low enough level at which

bioeffects are not generated while diagnostic information is being accumulated. The

total energy is controlled by output intensity and total radiation time. The output intensity

necessary for examinations differs depending on the patient and the clinical case.

Not all examinations can be performed with an extremely low level of acoustic energy.

Controlling the acoustic level at an extremely low level leads to low-quality images or

insufficient Doppler signals, adversely affecting the reliability of the diagnosis. However,

increasing the acoustic power more than necessary does not always contribute to an

increase in quality of information required for diagnosis, rather increasing the risk of

generating bioeffects.

Users must take responsibility for the safety of patients and utilize ultrasound

deliberately. Deliberate use of ultrasound means that output power of ultrasound must

be selected based on ALARA.

Additional information regarding the concept of ALARA and the possible bioeffects of

Ultrasound is available in a document from the AIUM (American Institute of Ultrasound

Medicine) title “Medical Ultrasound Safety”.

21.4 MI/TI Explanation

21.4.1 Basic knowledge of MI and TI

(1) Mechanical bioeffect and thermal bioeffect

The relationship of various ultrasound output parameters (frequency, acoustic pressure

and intensity, etc) to bioeffects is not fully understood presently. It is recognized that two

fundamental mechanisms may induce bioeffects. One is a thermal bioeffect with tissue

absorption of ultrasound, and another one is a mechanical bioeffect based on

cavitations. Thermal Index (TI) gives the relative index of temperature increase by

thermal bioeffect, and Mechanical Index (MI) gives the relative index of mechanical

bioeffect. TI and MI indices reflect instantaneous output conditions, so they do not

consider the cumulative effects of the total examination time. TI and MI models contain

practical simplifications to complex bioeffects interaction. Then the operator should be



Acoustic Output

21-3

aware that the actual worst case temperature rise may be up to several times higher

than the displayed TI value.

MI (Mechanical Index):

The mechanical bioeffects are the result of compression and decompression of

insonated tissues with the formation of micro bubbles that may be referred to as

cavitations.

MI is an index that shows the possibility of the cavitations generation based on acoustic

pressure, and the value in which the peak-rarefactional acoustic pressure is divided by

the square root of the frequency. Therefore MI value becomes smaller when the

frequency is higher or the peak- rarefactional acoustic pressure is lower, it becomes

difficult to generate the cavitations.

Pr, α MI =

awf f × CMI

,

CMI = 1 (MPa / MHz )

For the frequency 1 MHz and the peak-rarefactional acoustic pressure 1 MPa, MI

becomes 1. It is possible to think MI to be one threshold of the cavitations generation.

Especially, it is important to keep MI value to be low when both gases and the soft

tissues exist together, for such as lung exposure in cardiac scanning and bowel gas in

abdominal scanning.

TI (Thermal Index):

TI is determined by the ratio of the total acoustic power to the acoustic power required

to raise the tissue temperature by 1 degree C. In addition, because the temperature

rises is greatly different according to tissue structures, TI is divided three kinds: TIS

(Soft-tissue Thermal Index), TIB (Bone Thermal Index) and TIC (Cranial-bone Thermal

Index).

TIS: Thermal index related to soft tissues, such as abdominal and cardiac applications.

TIB: Thermal index for applications, such as fetal (second and third trimester) or

neonatal cephalic (through the fontanel), in which the ultrasound beam passes

through soft tissue and a focal region is in the immediate vicinity of bone.

TIC: Thermal index for applications, such as pediatric and adult cranial applications, in

which the ultrasound beam passes through bone near the beam entrance into the

body.



Acoustic Output

21-4

Although the output power is automatically controlled for the selected applications, high

TI values should be keep to a minimum or avoided in obstetric applications. WFUMB

(World Federation for Ultrasound in Medicine and Biology) guidelines: state that

temperature increase of 4 degree C for 5 min or more should be considered as

potentially hazardous to embryonic and fetal tissue.

(2) MI/TI

The smaller the MI/TI values, the lower the bioeffects.

21.4.2 MI/TI display

TI and MI values are displayed in real time in the lower part of the screen. The operator

should monitor these index values during examinations and insure that exposure time

and output values are maintained at the minimum amounts needed for effective

diagnosis.

Under different operating conditions, once there is a situation that a MI value is greater

than 1.0; the start point of displaying MI values is 0.4.

In the same way, once there is a situation that a TI value is greater than 1.0, the TI

value will be displayed and the start point is 0.4. The user can set which TI item is to be

displayed in the preset. Open the "B/THI" page in [Image Parameter] dialogue, and the

acoustic output setups appear, as shown in the figure below:

Here the user can preset TIC, TIB or TIS to be displayed, as well as the level of

acoustic power. Generally speaking, when a cranial exam is performed, TIC is preset to

be displayed only.

NOTE: If there is a value of MI or TI exceeds 1.0, user must be careful to practice

ALARA principle.

The display precision is 0.1.

21.5 Acoustic Power Setting

Acoustic power adjustment

Turn the 『 A.Power 』 knob on the main panel to adjust the acoustic power, and the

current level is displayed in the lower part of the screen. The higher the acoustic power

level, the larger the current acoustic output.

When the image is frozen, the system stops transmitting acoustic power.

Default setting of acoustic power

Selection of diagnostic applications is the most important factor for controlling

ultrasound output.

The permissible level of intensity of ultrasound differs depending on the region of

interest. For fetal examinations, in particular, much care must be exercised.

In this system, imaging presets can be created using the ultrasound output set by the

user. At this time, the default function is disabled.

Any changes to the default setting value are the responsibility of the user.

Default choices

Initial power 0% to 100%*

* Definition of 100%:

The maximum acoustic power of a transducer determined by the increase in

transducer surface temperature in the selected mode and the acoustic power

restrictions specified by the FDA.

* Any value less than 1% is displayed as 0%.

NOTE： This system automatically returns to the preset values whenever changes are

made to the values (Power ON, Transducer Switch, New Patient, or Return

from Preset). In the factory default status, the Acoustic Output is limited below

preset values. Following the ALARA restriction, the user is allowed to increase the

acoustic power by A.Power knob clockwise under track3 limits and to preset it in

image parameter presets.

The acoustic output of the System has been measured and calculated in accordance

with the “Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment

(NEMA UD-2 2004) and the “Standard for Real-Time Display of Thermal and



Acoustic Output

21-6

Mechanical Indices on Diagnostic Ultrasound Equipment (AIUM and NEMA UD-3 2004).

21.6 Acoustic Power Control

The qualified operator may use the system controls to limit the ultrasound output and to

adjust the quality of the images. There are three categories of system controls relative

to output. They are (1.) Controls that have direct effect on the output, (2.) Controls that

indirectly control output and (3.) Controls that are receiver controls

Direct Controls:

It is possible to control, if necessary, the acoustic output with toggle switch “Acoustic

Power” on the operation panel. In this case, the maximum value of the acoustic output

never exceeds an MI of 1.9 and an ISPTA.3 of 720 mW/cm2

in any mode of operation.

Indirect Controls:

The controls that indirectly affect output are many imaging parameters. There are

operating mode, frequency, focal point and depth.

The operating mode determines whether ultrasound beam is scanning or

non-scanning. Thermal bioeffect is closely concerned with M, PW Doppler and Color

Doppler mode. Acoustic attenuation of tissue is directly related to transducer frequency.

The focal point is related to active aperture of transducer and beam width. For the

higher PRF (pulse repetition frequency), the more output pulses occur over a period of

time.

Receiver Controls:

The receiver controls (for example, gain, dynamic range, and enhance, etc.) do not

affect output. They should be used, if possible, to improve the image quality before

using controls that directly or indirectly affect output.

21.7 Acoustic Output

21.7.1 Derated Ultrasonic Output Parameters

In order to determine the relevant Ultrasonic Output Parameters, a method is used

which allows for the comparison of ultrasound systems which operate at different

frequencies and are focused at different depths. This approach, called "derating" or

"attenuating", adjusts the acoustic output as measured in a water tank to account for the

effect of ultrasound propagation through tissue. By convention, a specific average

intensity attenuation value is used, which corresponds to a loss of 0.3 dB/cm/MHz.

That is, the intensity of ultrasound will be reduced by 0.3 dB/MHz for every centimeter of

travel from the transducer. This can be expressed by the following equation:

)10/3.0(10

z f

water attenc x I I ××

=－

Where Iatten is the attenuated intensity, Iwater is the intensity measured in a water tank

(at distance z), fc is the center frequency of the ultrasound wave (as measured in water),

and z is the distance from the transducer. The equation for attenuating pressure

values is similar except that the attenuation coefficient is 0.15 dB/cm/MHz, or one-half

the intensity coefficient. The intensity coefficient is double the pressure coefficient

because intensity is proportional to the square of pressure.

Although the attenuation coefficient chosen, 0.3 dB/cm/MHz, is significantly lower than

any specific solid tissue in the body, this value was chosen to account for fetal

examinations. In early trimester ultrasound fetal examinations, there may be a

significant fluid path between the transducer and the fetus, and the attenuation of fluid is

very small. Therefore the attenuation coefficient was lowered to account for this case.

21.7.2 Limits of acoustic output

In accordance with the FDA Track 3 requirements, the derating (or attenuated)

approach was incorporated into the FDA Acoustic Output Limits, as listed below. The

maximum acoustic output level from any transducer in any operating mode is expected

to fall below these limits.

21.7.3 Differences between actual and displayed MI and TI

In operation, the system will display to the operator the Acoustic Output Parameters

Thermal Index, TI, or Mechanical Index, MI (or sometimes both parameters

simultaneously). These parameters were developed as general indicators of risk from

either thermal or mechanical action of the ultrasound wave. They serve to indicate to

the operator whether a particular setting of the system increases or decreases the

possibility of Thermal or Mechanical effect. More specifically, they were designed to

assist in the implementation of the ALARA principle. As an operator changes a given

system control, the potential effect of the change in output will be indicated. However,

the Thermal Index is not the same as temperature rise in the body, for several reasons.

First of all, in order to provide a single display index to the user, a number of simplifying

assumptions had to be made. The biggest assumption was the use of the attenuating

formula described above, which is much lower that the actual value for most tissues

within the body. Scanning through muscle or organ tissue, for example, will produce

much higher attenuation than0.3 dB/cm/MHz. There were also significant simplifications

made for the thermal properties of tissue. Therefore, scanning through highly perfused

tissue, such as the heart or vasculature, will produce significantly less thermal effect

than that suggested by the Thermal Index.

Similarly, the Mechanical Index was derived to indicate the relative possibility of

mechanical (cavitation) effects. The MI is based on the derated peak rarefactional

pressure and the center frequency of the ultrasound wave. The actual peak

rarefactional pressure is affected by the actual attenuation caused by tissue in the path

between the transducer and the focal point. Again, all solid tissues within the body

have higher attenuation than the proscribed 0.3 dB/cm/MHz value, and therefore, the

actual peak rarefactional pressure will be lower. Further, the actual peak rarefactional

pressure will change depending upon the region of the body being scanned.

For these reasons, the TI and MI displays should only be used to assist the operator in

implementing ALARA at the time of the patient examination.
