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 Abdomen, Other, and SP), so 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 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.

[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 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 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 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 sections. This section consists of 104 pages. 1-1

In order to obtain correct ultrasonic measurement results, the computation equations and patient management database are decided according to the application selected.

The measurement values are updated in real time until the measurement operation is finalized. Up to 10 caliper marks can be displayed in the measurement results display area. Section 1-4-1-1. “Starting from the + switch”. Section 1-4-1-3. “Starting from the MEASUREMENT switch”. Section 1-4-1-4. “Starting from a Hot key”. Section 1-4-1-5. “Starting from the USER switch”.

Report (When the application is Abdomen, OB, GYN, Cardio, Vascular or Uro) →

The measurement values displayed on the report screen can be set with the preset function to either the most recent values or an average. Also, up to six of these measurement values can be preset for each measurement item. (For an explanation of each item, see the pages for each application.)

[Remark] The SSD-4000 has the following three functions for recording the results of examinations. a.

When operation (4) above is performed and a report is displayed, it is recorded by the recording device (thermal printer) connected to the SSD-4000.

b.

The report can be printed on paper using Printer in the Output function of the Report screen.

c.

The measurement results can be transmitted to the application software in an external personal computer using PC in the Output function of the Report screen.

(2)

Select the basic measurement item executed with Rotary Encoder 1 and execute it.

(3)

After measurement, to measure again, press the + switch. →

The last measurement is started.

[Remark] Pressing the CANCEL switch returns the system to the status before separation without finalizing the measured caliper mark. If the CANCEL switch is pressed before the caliper mark is separated, that mark is erased.

1-4-1-2.

Starting measurement with a compound mode image

Pressing the + switch on hybrid modes (B/M and B/D modes), the measurement corresponding to each ultrasound image (B, M, and D) is performed. For example, for B/M mode as in the figure below, when the + switch is pressed, the caliper mark is displayed on the M image with a priority order (D → M → B). The caliper mark is moved to the B image side with the trackball. The moment at which the caliper mark is moved into the B image becomes DIST. The measurement items and control menu display at the bottom of the screen also change to that for the B image. Moving the + mark to the B (M) image with the trackball

Erasing individual marks

When executing multiple basic measurements and erasing the finalization mark results individually, select SELch on the control menu, then press the SET switch. Move the arrow mark in the results display to the measurement results to be erased, then press the SET switch again. The caliper mark is now ready for re-measurement. Furthermore, when the CANCEL switch is pressed, the caliper mark and measurement results are erased. To erase only the mark being executed, press the CANCEL switch on the operation panel twice. If measurement has not yet been carried out (when there is one mark), pressing the CANCEL switch ends the measurement function.

1-4-1-7.

Ending a measurement function

The measurement marks and results on the screen are erased in the following cases. • When you press (selected) the CLEAR switch • When you press the SET switch after selecting Clear in the measurement menu • When you press the MEASUREMENT switch twice in succession • When you cancel a freeze status [Remark] The above applies only when the Caliper auto off function in the Preset menu is ON.

1-6.

Executing Application Measurement Using Transfer Function The transfer function transfers the results of basic measurement to the application measurement side and registers them in reports. Various application measurements can be completed without executing application measurement through the measurement menu by carrying out basic measurement with the + switch and using the transfer function. Here is an explanation using an example of transfer to Uterus measurement of gynecological measurement. (1)

Press the + switch. →

(2)

Select DIST, measure the uterus length, then press the SET switch.

Use the trackball to move the arrow mark displayed in the control menu to the measurement results display area. →

The transfer destination list is displayed.

[Remark] When there are a number of measurement results, move the arrow to the result that you wish to transfer, and press the SET switch. The arrow will move to the transfer destination list. (3)

Select Ut-L as the transfer destination, then press the SET switch. →

The measurement results of (1) are transferred to the Uterus measurement Length. Repeating these operations for Ut-AP and Ut-W completes the uterus measurements.

[Remark] The numbers displayed in parentheses ( ) in the transfer list show the number of reports registered.
