Ultrasonic imaging system adapted for use with ultrasonic probes having different center frequencies

摘要: Disclosed herein is an ultrasonic diagnostic apparatus employing two or more probes each comprising a plurality of transducers for transmitting and receiving wave, the further comprising: first storage means storing only standard focus data, that is, data forming received beams employed in predetermined one probes; second ratio center frequency to another calculation calculating other probe from stored form image waves by probe, wherein any used focusing into pieces digital signal delaying delay time, delayed are finally added up image.
