ABSTRACT:
An ultrasonic transducer system comprising a transducer array, control circuit and display system wherein the control system is able to actuate the transducer elements in groups of N and N+1 elements, actuate the groups in non-sequential order, actuate groups of selectively different sizes, subject the actuation signals to and the echo signals from the transducers to pre-programmable delay periods, compress the echo signals into a logarithmic representation, transform the echo signals into plural simultaneous visual displays on a standard TV monitor in split screen format, and transform the display of discrete points in the visual display into continuous lines. Further, each transducer element in the array may consist of a split or paired set of transducers.
