2.Abdominal Measurement 2-2.Abdominal Measurement Functional Outline

2-2-2. Items of Particular Note For blood flow velocity measurement: When recording an arterial flow Doppler waveform (pulse method), if the Doppler incident angle exceeds 60× the measurement error becomes large. The measured values of the blood flow values obtained using this equipment are the absolute values displayed on the observation monitor. They are controlled as positive and negative values for the purpose of calculating the arithmetic index. If the display of each measured value in a report is set to “Average” in a preset, the positive and negative values are added together and displayed as a mean value. Consequently, when performing multiple measurements of blood flow on the blood flow waveform drawn using the color Doppler method as a guide, use identical recording conditions (forward and reverse flow directions) for all of the blood flow waveforms in order to correctly display each of the arithmetic values arranged in the report.

Record a slice image of the pancreas showing the pancreatic duct in the B mode.

(2)

Select the P-Duct on the touch panel. The + mark is displayed, so measure the pancreatic duct.

(3)

Press the SEND switch. Measurement is finalized.

Renal volume measurement

Approximate each of the left and right renal volume to an ellipsoid, measure the major and minor axes of the transverse image (Width, A-P) and the length of the major axis of the longitudinal image (Length), and calculate the volume of each renal.

A-P Length

Width

Longitudinal Image

Transverse Image

[Remark] Measure these three axes in such a way that they intersect each other. The switching between the Right and Left can be made with the touch panel. The operation procedure for both kinds of measurement is the same.

<Operation method> The case of the Right of the Renal Volume is explained. (1)

Display the longitudinal and transverse images of the right kidney in the 2B mode.

(2)

Select the Right of the Renal Volume on the touch panel. →The + mark is displayed, so measure the Length using the longitudinal image.

(3)

Press the + switch. →Measure the Width using the transverse image.

(4)

Press the + switch. →Measure the A-P using the transverse image. Volume (Rt.Renal Vol.) is computed.

(5)

Press the SEND switch. →Measurement is finalized.

Spleen measurement

This measurement is for obtaining the spleen index (SI = axb) from the major diameter (a) and the thickness (b) of the spleen.

<Operation method> (1)

Record a slice image of the spleen in the B mode.

(2)

Select the Spleen on the touch panel. A + mark appears, so measure the major diameter a.

(3)

b

Press the + switch. Measure the thickness b.

SOL (Space Occupying Lesions) measurement

This is the measurement of the length of the three axes of a space-occupying lesion, such as a tumor, for calculating the volume of the lesion using an elliptical approximation. The same operation is used for both SOL1 and SOL2.

<Operation method> (1)

Record a slice image showing the SOL in the 2B mode.

(2)

Select the SOL1 on the touch panel.

Diam1

A + mark appears, so measure the first axis. (3)

Diam2

Press the + switch.

Diam3

Measure the second axis. (4)

Press the + switch. Measure the third axis.

(5)

Press the SEND switch. Measurement is finalized.
