Image Optimization 5-95
5.14.1.6 Cine Review
Press <Freeze> or open an elastography imaging cine file to enter cine review status.
5.14.2 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.
STE imaging is an option.
L11-3U, L14-6WU, L14-5WU, L9-3U, SC5-1U, C5-1U, SC6-1U probes support the STE imaging.
5.14.2.1 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 <Elasto> or press the user-defined key (set the
user-
defined key via [Preset]→[System]→[Key Config]) 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 (for details, refer to “5.14.2.2 STE Mode Image Optimization”).
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.

Image Quality
Description
Used to select the transmitting frequency of the current probe, the real-time value of
which is displayed in the image parameter area in the upper right side of the screen.
Operation
Tap [E Quality] on the touch screen to select the different THI frequency value.
