Abstract
An electronic signal processing device which forms a compound image for any pulse-echo ultrasound imaging system using a two-dimensional array transducer. The processing device obtains the detected sum of a series of cross-shaped apertures within the transducer in order to form a spatial compound image with the output of each cross-shaped aperture consisting of the product of the output signals from the orthogonal arms of the cross.
