PROBLEM TO BE SOLVED: To realize an ultrasonic diagnostic equipment improved in reaching and resolution at a far point direction even if an ultrasonic probe whose aperture area is restricted is used. SOLUTION: The ultrasonic diagnostic equipment 1 comprises an oscillator array 9 composed of a plurality of oscillator elements, whose actual aperture can be expanded, a rotating actuator 12 to actuate the oscillator array 9 to rotate, a TG33 to generate a timing signal in synchronizing with an angle of rotation by the rotating actuator 12, a transmitting circuit 34 to respectively output a transmit signal to each element of the oscillator array 9 so as to send a plurality of ultrasonic transmissions to one sound ray based on the timing signal generated by the TG33, a receiving circuit 35 to synthesize echo signals from a subject obtained by a plurality of the ultrasonic transmissions to one sound ray obtained at each element of the oscillator array 9 based on the timing signal generated by the TG33.
