ABSTRACT:
A three-dimensional region of an object is scanned with at least one pulsed ultrasonic beam. Echo signals are generated, which represent echoes that have originated within said region in response to said beam. By a switching operation in accordance with at least one logical function, those of said echo signals are selected which represent echoes that have originated at at least one locus that is defined by said at least one logical function. Each of the thus selected echo signals is displayed at a location which is coordinated with the location at which the echo represented by said signal has originated.
