Abstract

According to one embodiment, an ultrasonic diagnostic apparatus includes an imaging system, a biological signal receiving system and a biological signal acquisition apparatus. The imaging system is configured to acquire ultrasonic image data by transmitting and receiving an ultrasonic wave to and from an object. The biological signal receiving system is configured to wirelessly transmit a transmission request of a biological signal of the object, receive the biological signal of the object wirelessly transmitted as a response to the transmission request, and output the received biological signal to an output unit. The transmission request is transmitted to a biological signal acquisition apparatus. The biological signal acquisition apparatus control system is configured to wirelessly transmit information according to an operating condition of at least one of the imaging system and the biological signal receiving system. The information is transmitted to the biological signal acquisition apparatus.
