11. Tap [Elasto] > [STQ] on the touch screen. Or press the user-defined <STQ> key to enter the
STQ mode.
12. Adjust the ROI based on the lesion size and the position.
13. 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.
14. Freeze the image, and replay the image if necessary.
15. Save the single-frame and multi-frame image.
16. Reacquire the image if necessary.
17. Press <B> on the control panel or tap [Elasto] on the touch screen to exit the elastography

Rotate [Fixed ROI] knob to adjust the ROI fixed size.
The cross “+” shows the center of the ROI, and the depth appears at the right bottom of the screen.
Elas. Metric
Display the changes of elasto metric’s average value inside the ROI by elasto curve. It is convenient
to the doctor to choose the stable measurement result.
