6 - 10 Operator’s Manual
6 Image Acquisition
Curved anatomical M image in the operator’s manual that it is provided for
reference, not for confirming a diagnosis. Generally it should be compared with
other device or make a diagnosis by non-ultrasonic methods.
Only phased probe supports Free Xros CM.
Perform the following procedure:
1. In real-time 2D mode, adjust the probe and image to obtain the desired plane.
2. Press <TDI> to obtain the image.
3. Tap [Free Xros CM] on the touch screen to enter the mode.
4. Use the trackball/trackpad to define the start point of the sampling line on the 2D image.
The cursor displays as +, and can be moved within the 2D image only.
5. Press <Set> to fix the start point, and the digital number “1” is marked beside the point.
6. Define the next point using the trackball/trackpad and <Set> key (tap [Undo] on the touch
screen to cancel the current point and activate the preview point). The system updates the time-
motion curve in real time, and each point is marked with a number in sequence.
7. Repeat Step 6 to finish the sampling line.
8. Double press <Set> to finish the editing.
9. You can edit the curve if needed:
a. After finishing the sampling line, tap [Edit] on the touch screen. The cursor becomes the
icon .
b. Move the cursor over the curve, press <Set> to activate the spot.
c. Move the cursor to change the shape of the curve.
d. Double press <Set> to finish the editing.
NOTE:
Tap [Delete] on the touch screen to remove the curve, and tap [Edit] to re-edit the curve.
10. Adjust the parameters to obtain the desired tissue of Free Xros CM image. Then, save the
image.
11. Tap [Free Xros CM] or press the user-defined key for “Free Xros CM”, or press <B> to exit.
6.6.3 Anatomical M Mode Parameters
In anatomical M mode, adjustable parameters are similar with these in M mode.
6.7 PW/CW Mode
PW (Pulsed Wave Doppler) mode or CW (Continuous Wave Doppler) mode is used to provide
blood flow velocity and direction utilizing a real-time spectral display. The horizontal axis
represents time, while the vertical axis represents Doppler frequency shift.
