<P>PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic system capable of enhancing the SN ratio of a higher harmonic component even in a case that volume scanning is performed by a two-dimensional ultrasonic probe. Ž<P>SOLUTION: The ultrasonic diagnostic system S is equipped with: the two-dimensional ultrasonic probe 2 containing a plurality of piezoelectric elements arranged in a two-dimensional array state; a transmission part 12 for outputting a transmitting electric signal to the ultrasonic probe 2 so as to transmit a first ultrasonic signal into a specimen; a receiving part 13 for receiving a receiving electric signal obtained by converting the ultrasonic wave received by the ultrasonic probe 2; a correlation part 14 for detecting the receiving electric signal of a second ultrasonic signal coming from the inside of the specimen based on the first ultrasonic signal from the output of the receiving part 13 by performing the correlational processing of the output of the receiving part 13 and a preset reference signal; and an image processing part 15 for forming the internal image of the specimen on the basis of the receiving electric signal of the second ultrasonic signal detected by the correlation part 14. The transmitting electric signal is encoded by a predetermined system. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
