Abstract: Apparatus for the parallel processing of ultrasonic information to derive simultaneously multiple vectors of ultrasonic information per ultrasonic transmission. In a preferred embodiment, the apparatus includes for each transducer element in a transducer array an analog to digital converter and a delay processing subsystem associated with each analog to digital converter. Each delay processing subsystem includes means for applying a main delay time period to each received digitized signal and a first and a second incremental time delay means for delaying by some additional incremental time period the digitized main delay signal.
