6 Image Acquisition
Operator’s Manual 6 - 23
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.
• Only after the user chooses the image review, the quantitative analysis is available. If
the user chooses the static image (only one frame), the quantitative analysis is not
available.
2. Tap [TDI QA] or press the user-defined key for “TDI QA” to enable the function.
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
• Use the trackball; 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.
3 Display analysis
curve
• Y-axis represents the velocity (unit: cm/s) [in strain-time curve, Y-
axis represents the strain (%); in strain rate-time curve, Y-axis
represents the strain rate (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 using the trackball.
• 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 moving the cursor onto
one point on the curve; and if you press <Set> at this time, the frame
marker will move to the spot.
