An ultrasonic diagnostic system comprises: a first transceiver for performing transmission/reception of first ultrasound for detecting shear waves generated in a subject by mechanical vibration a second transceiver for performing transmission/reception of second ultrasound to/from the subject a computing section for calculating a value of a parameter affecting a frequency of the first ultrasound to be transmitted from the first transceiver based on echo signals obtained by transmission/reception of the second ultrasound an identifying section for identifying one first transceiver from among a plurality of kinds of first transceivers each having a different frequency of said first ultrasound based on the value of said parameter and a display device for displaying the first transceiver identified by the identifying section.
