Ultrasonic Probe and Ultrasonic Diagnostic Apparatus

摘要

An ultrasonic probe includes a plurality of ultrasonic transducers. The ultrasonic probe is connected to a reception system circuit including at least one first delay adder circuit in which a predetermined number among the plurality of ultrasonic transducers is configured as one subarray and delaying and adding are performed in subarray units with respect to an ultrasonic wave reception signal that is acquired from the ultrasonic transducers included in the subarray, and a second delay adder circuit in which delaying and adding are performed with respect to the ultrasonic wave reception signal that is acquired from the ultrasonic transducers. The plurality of ultrasonic transducers include a first group which transmits the reception signal to the second delay adder circuit passing through the first delay adder circuit and a second group which transmits the reception signal directly to the second delay adder circuit without passing through the first delay adder circuit.
