1. MEASUREMENT FUNCTIONS

1-1.

Preface

The measurement functions of the SSD-ALPHA10 are divided by application (clinical area) into Abdomen, OB,

GYN, Cardio, Vascular, URO, eTRACKING, and Small Parts.

The measurement values found in ultrasonic examination are recorded and managed for each patient.

They are effective for evaluation of observation over time. In addition to selecting a measurement from the menu,

you can also transfer the results of a basic measurement to an applied measurement and compute the results of applied measurement.

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

measurement items for each application.

[Remark]

These application measurement functions are based on documents that indicate the clinical effectiveness of the measurements concerned.

Consequently, they use measurement conditions and special computation formulas.

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

refer to the relevant documents.

[Remark]

The application measurement functions of the SSD-ALPHA10 include a function called EXAM. HISTORY for performing a progress observation (development evaluation, treatment evaluation, and so on.).

This function records and manages measurement values and operation index values obtained during various ultrasonic examinations, and displays the results 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-ALPHA10 ultrasonic diagnostic instrument are described in the following sections.

Executing the Application Measurement Using the Transfer Function

The copying function is a function to transcribe fundamental measurement results to various application

measurements and to register the report.

Various application measurements can be completed without executing the application measurement through the

measurement menu by carrying out the basic measurement with the + switch and using the transfer function.

The case that was transcribed of basic measurement results that was transferred to an Uterus measurement of

a gynecologic measurement is explained as an example.

(1)

Measure with the Distance of the basic measurement, and select the Transfer on the touch panel.

→

(2)

The measurement menu of GYN (Gynecologic measurement) is displayed.

Select the Uterus on the menu.

The measurement procedure of the Caliper method

In this type of measurement, the start and end points of the measurement are set using the two caliper marks, and the

distance, time, blood flow velocity and also the index values that use these parameters (depth, circumferential length,

flow velocity ratio, pressure gradient, and so on.) are obtained.

(1)

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

(2)

Press the ENTER switch.

→

The measurement start point mark is fixed.

(3)

Using the trackball, move the separated mark to the end

point of measurement.

(4)

Once again press the ENTER switch.

→

You can switch between the start and end point

marks, and adjust the position of each mark using

the trackball.

[Remark]

When the CANCEL switch or the ch switch on the touch panel

is pressed, the mark returns to the state of (1) so that the measurement can be started again.

(5)

Press the

→

switch.

Measurement is finalized.

[Remark]

If you press the + switch without pressing the

switch, a new

mark will be displayed, enabling you to continue the measurement.

In this case, the previous measurement will be finalized.

Method of performing a measurement using Ellipse

In this type of measurement an ellipse is displayed, and the area, circumferential length, and length of the major and

minor axes are obtained.

(1)

Using the trackball, move the mark to one end (start point) of the major axis.

(2)

Press the ENTER switch.

An ellipse (Major axis diameter : Minor axis diameter is 2 : 1) is displayed.

Using the trackball, determine the position of the ellipse

by enlarging or reducing the minor axis diameter.

[Remark]

If you press the ENTER switch at this point in time, you can use

the trackball to adjust the position of each point.

Each time you press the ENTER switch, the point that you can

move with the trackball switches over in the sequence a → b →

c → b → a, enabling you to adjust the position of each point.

[Remark]

When the CANCEL switch or the ch switch on the touch panel

is pressed, the mark returns to the state of (1) so that the measurement can be started again.

[Remark]

The formulas for calculating area and circumferential length are

shown below.

Use the symbols in Fig.1 to define each operation index as

shown below.

X - ax : Distance between a and b

y - ax : Distance between c and c

As a result, the area and circumferential length are as follows.

Area = π /4 (X-ax) × (Y-ax)

Circ = π √ {[(X-ax)2 + (Y-ax)2] / 2}
