<p>An ultrasonic diagnostic apparatus includes an ultrasonic probe including a plurality of ultrasonic transducers, a transmission driving signal generating unit which generates transmission driving signals for forming a plurality of transmitting beams in one ultrasonic transmission and supplies the transmission driving signals to the respective ultrasonic transducers, a calculation unit which calculates delay times of the transmission driving signals for forming the transmitting beams for the respective ultrasonic transducers so as to arrange the respective transmitting beams in centers of fundamental receiving parallel/simultaneous beam groups with a plurality of receiving beams being a unit in which a plurality of receiving beams formed based on the reflected waves are arranged three-dimensionally at equal or equiangular intervals, and a control unit which controls the transmission driving signal generating unit based on each of the calculated delay times.</p> |
