Abstract
An acoustic imaging system capable of producing C-mode images or orthoscopic projection images of a three-dimensional volume at significantly increased speeds of operation is described. For each acoustic pulse transmitted by a piezoelectric transducer array an electronic parallel processing system produces several unique image points whose locations in the image correspond to the Cartesian coordinates of the positions of receiving transducers. While range information is not directly displayed, range discrimination can be realized by means of an optional range dependent gain control or an optional color display in which range discrimination occurs through visual discrimination of differing hues.
