About Strain Graph

The strain graph displays the variation over time of tissue strain caused by compression in real time. Pressing the tissue which you want to image so that the periods and amplitudes of the Strain Graph are constant makes it possible to create a stable Elasto Mode image.

Pressing probe (applying pressure to tissue) → Positive value Withdrawing probe (releasing pressure from tissue) → Negative value

* Stronger pressure increases the amplitude. Gentler pressure reduces the amplitude.

Strain Ratio

① Select a Str. Ratio from Measurement Menu. ② Move the cross cursor displayed in the center of the screen to

the desired starting point of ROI-A, and then press the ENTER key.

③ Move the next displayed cross cursor to the desired end point

of the ROI-A, and then press the ENTER key to draw the ROI. The measurement results are displayed when ROI-A is set.

④ A cross cursor appears outside ROI-A. Repeat steps 2 and 3

above to set ROI-B.

For the breast, setting the ROI as shown in the left figure allows you to estimate the strain in both the fat and lesion regions and then calculate the FLR, or the fat-lesion ratio.

A …The mean strain within the region surrounded by ROI-A B …The mean strain within the region surrounded by ROI-B B/A…The comparison of strain within ROI-A to ROI-B (Strain Ratio)

* The strain is expressed as a percentage (%). For example, if a

100-mm object has a strain of 1 mm, the strain is expressed as 1%.

Real-time Virtual Sonography (RVS) allows the real-time creation of cross-section (virtual) images that match the ultrasonic image reflecting the position and inclination of the probe. Cross-section images are retrieved out of the volume data (CT/MR/US) that has been captured beforehand. Virtual images are intended only for reference purposes. No puncture procedure or diagnosis must be determined based solely on the observation of the virtual image.

IMT measurement is the measurement to calculate the thickness of the internal media complex (IMC) of a carotid artery through automatic trace processing. “Trace method” and “three-point method”, which calculate only the mean value of three points are available.

How to set an ROI

Press Measurement Menu, and start L-IMT/R-IMT from the items displayed.

① Move and set the ROI to the position where

IMC is placed lower than the center of ROI.

② Set the positions A, B, and C of the three-point

measurement to the position where the blood vessel has no noise in its inside, and the IMC and tunica externa can be distinguished clearly.

③ Press ENTER key to fix the position of ROI.

Measurement result is displayed when ENTER key is pressed again.

Moving the ROI

Move the cursor into the ROI and press the ENTER key, and the ROI becomes movable. Press

ENTER again to fix the ROI.
