1. MEASUREMENT FUNCTIONS

1-1. Preface

The measurement functions of the SSD-4000 are divided by application (clinical area) into Abdomen, OB, GYN,

Cardio, Vascular, Uro, Small Parts, and Other.

The measurement values found in ultrasonic examination are recorded and managed for each patient (except for Ab-

domen, Other, and SP), so they are effective for evaluation of observation over time. In addition to selecting a mea-

surement from the menu, you can also transfer the results of basic measurement to applied measurement and

compute the results of applied measurement.

Also, the measurements available depend on the application, so there are ultrasonic studies that bring together the

measurement items for each application.

(Examples of studies for each application)

[Remark]

These application measurement functions are based on documents that indicate the clinical effectiveness of the mea-

surements concerned.

Consequently, they use measurement conditions and special computation formulas.

The abovementioned documents are listed at the end of the section on each application measurement function, so

refer to the relevant documents.

[Remark]

The application measurement functions of the SSD-4000 include a function called EXAM. HISTORY for perform-

ing a progress observation (development evaluation, treatment evaluation, and so on.).

This function records and manages measurement values and operation index values obtained during various ultra-

sonic examinations, and displays the results thereof as numerical values and/or graphs.

For this reason, in order to use this function correctly, be sure to enter the patient data using the ID screen before

performing an ultrasonic examination.

The various measurement functions of the SSD-4000 ultrasonic diagnostic equipment are described in the following

1-7-4-4. The measurement procedure of B-Trace method

In this type of measurement, a trace mark pattern is displayed, and the area and circumferential length are obtained.

(1) Using the trackball, move the mark to the measurement start point.


The measurement start mark is fixed.

(3) Using the trackball, move (trace) the separated mark along the boundary of the part to be measured.

[Remark]

At this point in time, if you rotate rotary encoder 1 on the operation panel, you can partially erase or re-display the

trace line.

If you rotate the rotary encoder counterclockwise, the trace line will be erased from the present position going

progressively toward the start point.

If you rotate the rotary encoder clockwise, the partially erased trace line will be re-displayed going progressively

toward the end point.

1-7-4-5. The measurement procedure of the Dop-Trace method

In this type of measurement, an ultrasonic Doppler waveform is traced, and the blood flow velocity at each point

along the trace, the time average blood flow velocity, the blood flow velocity ratio, the resistance index, the pulsa-

tility index, and so on, are obtained.

This method depends upon the Doppler trace method (Auto, Manual) that is set in advance using the preset function.

The factory setting is the Doppler Auto Trace function (Peak method).

1) Doppler Auto Trace method

The following is a description of the Doppler Auto Trace method using PI (Pulsatility Index) measurement as an

example.

(1) Set the Doppler waveform trace range.

Using the trackball, move the line cursor (vertical line) to the measurement start point.


The line cursor at the measurement start point is fixed.

(3) Using the trackball, move the line cursor (vertical line) to the measurement end point.


31/294

MN1-1175 Rev


1-23


The end point line cursor is fixed.

The points corresponding to the peak flow velocity (mean velocity) on the spectrum between these two lines are

automatically traced, and line cursors and the letters S and D appear at points PSV and EDV, respectively.

[Remark]

At this point in time, if you rotate rotary encoder 1 on the operation panel, you can adjust the position of the trace line.

If you rotate the rotary encoder counterclockwise, the trace line shifts progressively from the present position to-

ward the base line.

If you rotate the rotary encoder clockwise, the trace line shifts toward the point corresponding to the peak flow

velocity.

[Remark]

If you cannot perform adjustment satisfactorily using rotary encoder 1, press the CANCEL(Auto Trace cancel)switch at this point in time to switch over to the Manual mode. For details of Manual Trace operation, refer to the

next sub-section.


The line cursor that can be moved (solid line type) switches over. Using the trackball, adjust the positionof the cursor.

(6) Press the SETswitch.

2) Doppler Manual Trace method

The following is a description of the Doppler Manual Trace method using PI (Pulsatility Index) measurement as an

example.Pulsatility Index

(1) Using the trackball, move the mark to the start point of measurement.


The measurement start point mark is fixed.

(3) Using the trackball, trace the spectrum.

Use the systolic peak blood flow velocity (PSV) and the end-diastolic blood flow velocity (EDV) for comput-

ing PI and RI.

There are reports to the effect that the end-diastolic minimum blood flow velocity is also used for theseindexes.

The diastolic blood flow velocity and the end-diastolic minimum blood flow velocity do not necessarily

match each other.

Consequently, when starting these measurements, move the phase of EDV to the end-diastole or minimum

blood flow velocity point.

Calculate PI and RI at the blood flow velocity at these points.

1-9-1-3. Volume (Volume 1, 2)

You can measure volume by using the Caliper method or the Ellipse method (or a combination thereof).

(Refer to 1-7-4-1.,1-7-4-2.)

Volume1 and 2 measurement can be selected from the following method.

Spheroidal : Three diameters (long axis, short axis and the maximum cross-sectional diameter in the directionperpendicular to the long axis (= intermediate axis diameter)) are obtained from the image of two

orthogonally intersecting cross-sectional planes and the volume of the rotating ellipsoid is found.

Prolate : The volume is calculated by finding the major axis and minor axis of the ellipse in the same way

as for measuring the area of an ellipse and measuring the hypothetical circle on the cross-sectional

plane perpendicular to the minor axis.

Area-length : The cross-section for the major axis is traced, its surface area and length calculated, and the vol-

ume computed.

BP Simpson : The volume is computed using the basic principles of the Disk method. (2 view are measured.)

SP Simpson : The volume is computed using the basic principles of the Disk method. (1 view is measured.)

[Remark]

When performing Volume measurement using this equipment, you can display up to two formulas on the measure-

ment menu.For each of Volume 1 and 2, you can set
