Abstract: An ultrasonic diagnostic apparatus in accordance with the invention includes: an ultrasonic probe configured to transmit an ultrasonic wave to an object to be tested and receiving an ultrasonic wave from the object; an ultrasonic transmitter/receiver configured to provide a signal that causes the ultrasonic probe to transmit an ultrasonic wave and signal-processing a signal received from the object by the ultrasonic probe; an ultrasonic image constructor configured to construct an ultrasonic image from the signal-processed received signal; an image display for displaying the ultrasonic image; a controller configured to control the ultrasonic transmitter/receiver, the ultrasonic image constructor and the image display to work properly; and a temperature sensor, provided on the ultrasonic probe, configured to sense the temperature of the ultrasonic probe and outputting the sensed temperature to the controller.
Abstract: An ultrasonic probe suitable for reducing reflected waves returning from a rear surface part to a transducer side, and an ultrasonic diagnostic apparatus. Ultrasonic probe 1 comprises transducer 10 transmitting and receiving ultrasonic waves to and from a subject, a backing material 12 disposed on the rear side of the transducer 10, and heat dissipating block 14 stacked on the backside of the backing material 12. At least one of the backing material 12 and heat-dissipating block 14 comprises void 16 therein. A sound absorbing material 18 is desirably filled in void 16.
