6.5.2 CM Image Parameters
In CM mode, parameters that can be adjusted are in accordance with those in B, M and Color
modes; please refer to relevant sections of B, Color and M mode for details.
The ROI size and position determine the size and position of the color flow displayed in the color
M mode image.
6.6 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 in 2D imaging
modes.
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.
6.6.1 Linear Anatomical M (Free Xros M)
Free Xros M imaging is supported on frozen B image, B+M image and B+Power/Color 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] to enter Free Xros M mode.
3. Adjust the sampling line to obtain optimized images and necessary information.
– Position Adjustment: When the M-mark line is activated, tap the dotted circle and drag the
sampling line to change the position. The direction is recognized by the arrow at the end
of the line.
– Angle Adjustment: When the M-mark line is activated, tap the dotted circle and drag
along the sampling line to adjust the fulcrum of the line, and adjust the angle by rotating
the sampling line.
4. Tap [Image] to open the image menu. Adjust the parameters to optimize the image.
6.6.2 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 spectrum display. The horizontal axis
represents time, while the vertical axis represents Doppler frequency shift.
PW mode provides a function for examining flow at one specific site for its velocity, direction and
features. CW mode proves to be much more sensitive to high-velocity flow display. Thus, a
combination of both modes will contribute to a much more accurate analysis.
