Operator’s Manual 6 - 23
6.8 Anatomical M Mode
For an image in the traditional M mode, the M-mark line goes along the beams transmitted from the
probe. Thus it is difficult to obtain a good plane for difficult-to-image patients who cannot be
moved easily. However, in the Anatomical M mode, you can manipulate the M-mark line and move
it to any position at desired angles. The system supports anatomical M scanning (including Free
Xros M mode and Free Xros CM mode) in 2D imaging modes (B, Color, Power and TVI mode).
Anatomical M Mode and Color Anatomical M mode images are provided for
reference only, not for confirming diagnoses. Compare the image with those of
other machines, or make diagnoses using non-ultrasound methods.
6.8.1 Free Xros M
Free Xros M imaging is supported on frozen B image, B+M image and B+Power/Color/TVI image.
Perform the following procedure:
1. Adjust the probe and image to obtain the desired plane in real-time B mode or M mode.
Or select the B mode cine file to be observed.
2. Tap [Free Xros M] on the touch screen to enter Free Xros M mode or press the user-defined
key to enter Free Xros M mode.
There are 3 M-mark lines available, each with a symbol of “A”, “B” or “C” at one end as
identification.
3. Adjust the sampling line (single line or couple of lines) to obtain optimized images and
necessary information.
– Tap [Show A], [Show B] or [Show C] on the touch screen to adjust the sampling line. The
corresponding sampling line and the Free Xros M image appear on the screen. Then,
activate the sampling line.
– Tap [Display Cur.] or [Display All] on the touch screen to select whether to display the
image of the current M-mark line or all.
You can choose to display the sampling line on the current image or all.
– Press <Set> to switch among the sampling lines and press <Cursor> to show the cursor.
– Position Adjustment: When the sampling line is activated, move the trackball to adjust the
position. The direction is recognized by the arrow at the end of the line.
– Angle Adjustment: When the sampling line is activated, move the trackball to adjust the
fulcrum of the line, and rotate the <Angle> knob to adjust the angle.
4. Adjust the image parameters to obtain optimized images.
5. Press <B> to return to real-time B mode.
6.8.2 Free Xros CM (Curved Anatomical M-Mode)
In Free Xros CM mode, the distance/time curve is generated from the sample line manually
depicted anywhere on the image. Free Xros CM is used for TVI and TEI modes.
