Mindray TEX20 Operator's Manual

6 Image Acquisition
Operator’s Manual 6 - 9
To provide a much clearer color flow image.
Use low PRF to observe low-velocity flows, and use high PRF to observe high-velocity flows.
ROI Adjustment
To adjust the width and position of ROI in Color mode.
When the ROI box is solid line, tap to change its position.
When the ROI box is dotted line, tap and drag to change the size.
Tap to switch between the solid line and the dotted line status.
The larger the ROI box is, the lower the frame rate becomes, and the lower the resolution and color
sensitivity will be.
Image Quality
Refers to the transmitting frequency in Doppler mode of the probe, the real-time value of which is
displayed in the image parameter area.
Flow State
Refers to optimizing the various flow states.
Persistence
This function is to adjust the temporal smooth to optimize the image.
Smooth
This feature is used to reject the noise and smooth the image.
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.
WF (Wall Filter)
It filters out low-velocity signals to provide effective information, and this function is used to adjust
the filtered frequency. The real-time value (WF) is displayed in the image parameter area.
Priority
This function is used to set levels of the flow display, to display the grayscale signal or color signal.
The color image is preferred with higher value; while grayscale signals are displayed with the lower
value.
Line Density
The function determines the quality and information of the image.
The higher the line density is, the higher the resolution becomes.
Invert
To set the display mode of the color flow. The color scale will be inverted when the function is
turned on.
B/C Align
To set and constrain the maximum width of the B mode image to that of the Color ROI.
