6 Image Acquisition
Operator’s Manual 6 - 7
Color Map
This feature indicates the display effect of power image. The maps in Power mode image are
grouped into two categories: Power maps and Directional Power maps.
• The Power maps provide information of blood flow, which are highly sensitive to the low-
velocity flows.
• The Directional Power maps provide information of flow direction.
Dynamic Range
This function is to adjust the transformation of echo intensity into color signal.
Increasing dynamic range will lead to higher sensitivity to low-power signals, thus enhances the
range of signals to display.
6.4 M Mode
6.4.1 M Mode Image Scanning
Perform the following procedure:
1. Select a high-quality image during B mode scanning, and adjust to position the area of interest
in the center of the B mode image.
2. Tap [M] on the right side of the operating panel to enter M sampling line status, and drag the
sampling line to the desired position.
3. Tap [M]/ [Update] or double-click the sampling line to enter M mode. You can then observe
the tissue motion along with the anatomical images of B mode. During the scanning process,
you can also adjust the sampling line accordingly when necessary.
4. Tap [Image] to open the image menu. Adjust the parameters to optimize the image.
6.4.2 M Mode Image Parameters
Gain
To adjust the gain of M mode image, the real-time gain value is displayed in the image parameter
area.
Increasing the gain will brighten the image and you can see more received signals. However, noise
may also be increased.
Display Format
To set the display format of B mode image and M mode image.
Adjust according to the actual situation and obtain a desired analysis through comparison.
Speed
This function is used to set the scan speed of M mode imaging, and the real-time speed value is
displayed in the image parameter area.
Tint Map
This function provides an imaging process based on color difference rather than gray distinction.
Gray Map
Adjusting grayscale contrast to optimize the image.
