Abstract
A method and an apparatus for segmenting three-dimensional projected velocity images by limiting the volume of velocity data projected onto the imaging planes. If the volume of interest contains flowing blood, i.e., an artery or vein, the Doppler shift present in the ultrasound reflected from the flowing blood can be detected and then used to limit the amount of velocity data which is projected. Only pixels having velocity values within a predetermined range are projected onto the imaging plane.
