An apparatus for three-dimensional visualization of an object or substance with particular utility for determining the presence of breast cancer contains a dual sensing head having two transducers connected to conventional B-scan equipment. The methodology of this apparatus is based on a new form of ultrasonic imaging that presents perspective views rather than tomograms (cross-sections). These two perspective views are obtained simultaneously by using a pair of cylindrically focused transducers in a scanning unit and are displayed on a monitoring scope in a split screen presentation, which, when viewed as a stereo pair, gives the operator a three-dimensional image of the interior of the scanned object.
