Abstract
Three dimensional ultrasonic images are formed by volume rendering using a 3D ultrasonic image data set. The data set may be acquired by rocking, sweeping, fanning or rotating a 2D image plane through the volume being scanned, or by steering beams in different angular directions from a two dimensional array of transducer elements. The polar data is volume rendered to form a 3D image by means of projected raylines which are warped to account for the angular geometry of the acquisition.
