ABSTRACT:
An ultrasonic transducer is rotated until the displayed vessel has the smallest area. The transducer is then tilted to various angles with respect to a normal to a surface to obtain area and velocity measurements of fluid flow inside a vessel in a body imaged. A least mean square error calculation is then performed to find the area and velocity that will minimize such error. The product of these two quantities is the estimated flow.
