5.14.1 Strain Elastography
CAUTION:
It is provided for reference, not for confirming a diagnosis.
It is produced based on the slight manual-pressure or human respiration in 2D real-time mode. The
tissue hardness of the mass can be determined by the image color and brightness. Besides, the relative
tissue hardness is displayed in quantitative manners.
The strain elastography is an option. Only the probes support the strain elastography:
The L11-3U/L14-6WU/L14-5WU probes support the strain elastography.
The L9-3U probe supports the strain elastography.
The L20-5U probe supports the strain elastography.
The V11-3HU/DE10-3U probe supports the strain elastography.
5.14.1.1 Basic Procedure for Strain Elastography
1. Perform 2D scan to locate the region.
2. Tap [Elasto]
[Strain] on the touch screen. Assign a user-defined key for Elastography via:
[Setup]
[System Preset]
[Key Config]. Adjust ROI according to the lesion size.
Press the probe according to the experiences and actual situation.
Adjust the image parameters to obtain optimized image and necessary information.
Adjust the image parameters to obtain optimized image.
Do measurement or add comment/body mark to the image if necessary.
3. Evaluate the result based on the information above.
4. Press <B> to return to B mode or another mode.
5.14.1.2 Enter/Exit
Enter
Select [Elasto]
[Strain] on the touch screen to enter the mode.
The system displays two dual B+E windows in real time. The left one is 2D image, and the right one
is elasto image.
Exit
Press <B> or tap [Elasto] to exit, and then return to B mode.
5.14.1.3 Strain Curve
The screen displays the pressure curve in real-time:
