1. An ultrasound system which produces diagnostic images of volumetric regions of the body comprising: a probe which acquires echo signals along scanlines which are angularly arrayed with respect to each other from a volumetric region; a data storage device responsive to the echo signals which stores 3D data acquired from the volumetric region; and a volume renderer responsive to the 3D data which renders a 3D image using projections through the 3D data which are warped to account for an angular acquisition geometry.
