Color box overlay
In Color Doppler Mode, the region of interest is located within the green color box
overlay.
Data is displayed in blue to display vascular flow moving away from the transducer
and red to display vascular flow moving toward the transducer.
The system applies the colors only to the image data within the color box.
Display maps and velocity scale
Two display maps are shown to the left of the image while in Color Doppler Mode. The
left column is the 2D display map. The right column is the color display map. It follows
the acronym BART color principle for Doppler imaging (Blue=Away from the
transducer, Red=Toward the transducer). In this principle, positive vascular flows are
indicated by colors in the red range. Negative flows are indicated by colors in the blue
range. Flow velocities for each direction increase from dark to light.
In Color Doppler, a velocity scale corresponding to the display map is shown to the
left of the display maps.
Priority indicator
Adjust the priority relationship between the overlay data and the background 2D data
so you can eliminate false readings, by using the
Priority control.
