8 Elastography
Operator’s Manual 8 - 3
When the E Average function is enabled or disabled, the elasto curve is displayed based on different
statistical amounts.
8.1.3 Mass Measurement
Press <Measure> to enter measurement status.
You can measure shell thick, strain ratio, strain-hist, etc.
For details, see “Advanced Volume”.
8.1.4 Cine Review
Press <Freeze> or open an elastography imaging cine file to enter cine review status.
8.2 STE Imaging (Sound Touch Elastography)
Keep the probe still to produce the elastography image in real-time STE 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. STE imaging provides you real elasto modulus for
quantification analysis.
8.2.1 Basic Procedures for STE Imaging
1. Select a proper probe. Perform 2D scan to locate the region.
2. Tap [Elasto] > [STE] on the touch screen. Or press the user-defined <STE> key to enter the
STE mode.
3. Adjust the ROI based on the lesion size, and press <Set> to adjust the ROI size and the
position. To compare the hardness between the lesion and the normal tissue, the ROI should
include the lesion and the normal tissue.
4. Keep the probe still to imaging, and adjust the parameter to obtain premium image.
5. Freeze the image, and replay the image if necessary.
6. Perform the measurement or add comment/body mark to the image if necessary.
7. Save the single-frame and multi-frame image.
8. Acquire high-quality image if necessary.
9. Press <B> on the control panel or tap [Elasto] on the touch screen to exit the shear wave
elastography mode, and return to B mode.
