ABSTRACT:
An ultrasonic diagnostic apparatus capable of quantitatively checking its performance. The ultrasonic diagnostic apparatus includes: an ultrasonic transmission unit; an ultrasonic reception unit; a signal processing unit for processing detection signals output from the ultrasonic reception unit to generate data; a first storage unit for storing data, which has been obtained by transmitting ultrasonic waves to a predetermined object and receiving ultrasonic echoes, as management data; a second storage unit for storing data, which has been obtained by transmitting ultrasonic waves to the predetermined object and receiving ultrasonic echoes when performance of the ultrasonic diagnostic apparatus is checked, as check data; a comparison unit for generating comparison data on the basis of both the management data and the check data; and an image display unit for displaying an image on the basis of the comparison data.
