5.13.3 STQ Imaging (Sound Touch Quantification)
The STQ imaging is an option.
The SC6-1E probe supports the STQ imaging in abdominal exam mode.
The L12-3E, L9-3E, and L14-5WE probes support the STQ imaging in small organ (breast, thyroid,
testes) and musculoskeletal exam modes.
5.13.3.1 Basic Procedures for the STQ Imaging
1. Select a proper probe. Perform 2D scan to locate the lesion.
2.
Tap [Elasto]→[STQ] on the touch screen, Or press the user-defined key (set the user-defined key via
[Preset]→[System]→[Key Config]) to enter the STQ imaging mode.
3. Adjust the ROI based on the lesion size and the position.
4. Press <Update> to generate the acquisition. Place the probe still with stable force (not pressing,
sweeping or moving the probe) to acquire the image. Adjust the B image parameters to obtain a
premium image.
The stress curve shows at the bottom of the screen after entering the real-time acquisition.
The following indices display besides end of the curve in real-time:

Elasto modulus inside the ROI of the current frame;

The mean value, maximum value, minimum value, SD value of shear velocity;

Depth value of the active elasto modulus.
5. Freeze the image, and replay the image if necessary.
6. Save the single-frame and multi-frame image.
7. Reacquire the image if necessary.
8. Press <B> on the control panel or tap [STQ] on the touch screen to exit the elastography imaging
mode, and return to B mode.
5.13.3.2 STQ Mode Image Optimization
Scale
Description Used to optimize the display effect of the elasto average metric inside ROI via
changing the Y-axis size.
Operation
Rotate [Scale] knob to adjust the value.
The adjusting range is: 0-9 in increment of 1.
Impacts
If elasto metric average value inside ROI of a certain frame image exceeds the
maximum scale on the elasto curve, elasto metric will display in the maximum scale
value.
Other parameters of the STQ imaging are the same to those of the STE imaging. For details, please
refer to "5.13.2.2 STE Mode Image Optimization".
5.14 Stress Echo
Stress Echo is an option.
The phased probes in cardiac exam modes support the Stress Echo.
