摘要： An ultrasonic diagnostic imaging system is provided which calibrates and quantifies colors of a color power Doppler display to produce quantified measurements of Doppler power intensity. The colors of a color power Doppler image are divided into discrete colors and each color assigned a quantified measure of the Doppler power intensity indicated by that color. When a user moves a cursor over the image the system compares the color of the pixel where the cursor is located with the range of colors and their quantified measures and produces a quantified measure of the Doppler power intensity at the location of the cursor. A line of such measures across a blood vessel can be used to plot a profile of Doppler power intensity across the vessel, and an index number which is a measure of perfusion in a region of the body is determined from an area of a color power Doppler image.
