Abstract:
1. An ultrasonic diagnostic apparatus comprising: an ultrasonic probe configured to transmit and receive an ultrasonic wave; a transmitter configured to supply a signal to the ultra sonic probe and from an ultrasonic beam; a receiver configured to receive a reception signal obtained by transmitting the ultrasonic beam to an object; a signal processor configured to form an ultrasonic image based on the reception signal; a display unit configured to display the ultrasonic image; and a control unit configured to control the transmitter, the receiver, the signal processor and the display unit, wherein the control unit comprises a setting unit configured to set an operation mode of the transmitter to a low power consumption operation mode or a high spatial resolution operation mode, and wherein the transmitter comprises a FET (Field Effect Transistor), and the low power consumption operation mode and the high spatial resolution operation mode of the transmitter are selected by controlling bias current to a source and a drain of the FET.
