6 - 14 Operator’s Manual
6 Image Acquisition
The sampling line is displayed for one procedure operation. Press <M> to enter M mode.
6.5.2 M Mode Image Parameters
In M mode scan, the image parameter area on the left side of the screen displays the real-time
parameter values as follows:
Gain
To adjust the gain of M mode image, the real-time gain value is displayed in the image parameter
area.
Rotate <M> knob clockwise to increase the gain, and anticlockwise to decrease.
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.
Speed changing makes it easier to identify disorders in cardiac cycles.
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.
Edge Enhance
This function is used to increase image profile, so as to distinguish the image boundary.
0 represents no edge enhance is turned on, and the bigger the value is, the stronger the effect
becomes.
Larger edge enhance may lead to noise increase.
Dynamic Range (Dyn Ra.)
Adjusts contrast resolution of an image, compresses or expands gray display range. The real-time
dynamic range value will be displayed on the image parameter area.
The more the dynamic range is, the more specified the information appears.
