Zusammenfassung:	A sub-beamforming method and apparatus are applied to a portable, one-dimensional ultrasonic imaging system. The sub-beamforming circuitry may be included in the probe s assembly housing the ultrasonic transducer, thus minimizing the number of signals that are communicated between the probe assembly and the portable processor included in the imaging system. Including the sub-beamformer in the probe assembly also relieves the portable processor of some of the signal processing tasks. The sub-beamforming apparatus may be implemented digitally or may be implemented using analog components.
