Abstract
An ultrasonic scanner is disclosed for examining a planar region of a patient. The scanner has a transducer for emitting ultrasonic waves into the planar region of a patient which is defined by an array of subregions separated by subregion boundaries and for transforming echoes received from the planar region into electronic diagnostic values, and an electromechanical device for producing an indication of the position and the angular orientation of the transducer. The scanner also has a main memory having a plurality of addresses corresponding to the subregions for storing such diagnostic value at an address corresponding to the represented subregion, and a CRT display for displaying the diagnostic values stored in the memory. The position indication and angular orientation indication are used for generating the memory address for the diagnostic values corresponding to each echo. The addresses are generated with an analog processor, accumulator and buffer.
