Controlling the Sensitivity
The Sensitivity setting controls the system’s ability to detect and image blood flow color
representation in the artery. Areas where the blood is moving faster are more yellow:
areas where the blood moves more slowly are red. The sensitivity can be increased to
intensify the color of slower moving areas of blood flow, or it can be decreased to
diminish the color of faster moving areas of blood flow. Use the up and down arrows
located in the Adjust Image screen to adjust the sensitivity value.
Setting the Region of Interest
Setting the Region of Interest restricts the flow detection to a particular area of the
ultrasound image. Use the up and down arrows located in the Adjust Image screen to
increase or decrease the Region of Interest setting. The Region of Interest circle on the
screen image will be adjusted to correspond to your selection.
Value mappings for the Region of Interest range from:

Setting 1, corresponds to an Region of Interest diameter of 3.80 mm

Setting 21, corresponds to a Region of Interest diameter of 13.96 mm
