Ultrasonic doppler power measurement and display system

摘要

The ultrasonic diagnostic imaging method involves calibrating and quantifying colours of a colour power Doppler display to produce quantified measurements of Doppler power intensity. The colours of a colour power Doppler image are divided into discrete colours and each colour assigned a quantified measure of the Doppler power intensity indicated by that colour. When a user moves a cursor over the image the system compares the colour of the pixel where the cursor is located with the range of colours 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 colour power Doppler image.
