Figure 6-1 Quantitative analysis display (taking velocity-time curve as the example)
Perform the following procedure:
1.
Scan the image with the moves of myocardium on, freeze the image and select the scan scope,
or open the image which includes the myocardium moves already.
NOTE:
•
The current image (in frozen state) and the saved image can be used in the quantitative
analysis.
1
TDI review
Sampling area: indicates the sampling position of the curve. The
sampling lines are marked with color numbers. It can mark 8
ROIs at most.
2
2D grey image review
•
Tap the screen; the images in TDI review window and 2D
review window are reviewed synchronously, since the two
images are frozen at the same time.
•
ROI movement is linked between the TDI (Tissue Doppler
Imaging) review window and the 2D imaging reviewing
window.

Display analysis curve
•
Y-axis represents the velocity (unit: cm/s) [in strain-time
curve, Y-axis represents the strain (%); in strain-time curve,
Y-axis represents the strain (unit: 1/s)].
•
X-axis represents time (s);
•
Frame mark: a white straight line perpendicular to the X-
axis, and can be moved left and right by tapping to the
desired place.
•
Click the check box in front of the ROI to display or hide the
analysis curve.
•
You can get the current X/Y axis value by tapping one point
on the curve; and the frame marker will move to the spot.
