More Information
Summary:This invention relates to ultrasonic diagnostic imaging systems and, in particular, to ultrasonic diagnostic imaging systems which produce volume rendered three dimensional images from polar coordinate image data. 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.
