Ultrasonic diagnostic apparatus and method of checking its performance
First Claim
1. An ultrasonic diagnostic apparatus comprising:
- ultrasonic transmission means for transmitting ultrasonic waves;
ultrasonic reception means for receiving ultrasonic echoes modulating light in accordance with the ultrasonic echoes and detecting the light so as to output detection signals;
signal processing means for processing the detection signals output from said ultrasonic reception means to generate data;
first storage means for storing the generated data as management data, said management data being obtained by transmitting ultrasonic waves to a predetermined object and receiving ultrasonic echoes reflected by said predetermined object;
second storage means for storing the generated data as check data, said check data being obtained by transmitting ultrasonic waves to said predetermined object and receiving ultrasonic echoes reflected by said predetermined object when performance of said ultrasonic diagnostic apparatus is checked;
comparison means for generating comparison data on the basis of both the management data stored in said first storage means and the check data stored in said second storage means; and
an image display unit for displaying an image on the basis of the comparison data generated by said comparison means.

6. A method of checking performance of an ultrasonic diagnostic apparatus, said method comprising the steps of:
-
(a) previously transmitting ultrasonic waves to a predetermined object and receiving ultrasonic echoes reflected by said predetermined object, modulating light in accordance with the ultrasonic echoes and detecting the light to generate data and store the generated data as management data;
(b) transmitting ultrasonic waves to said predetermined object and receiving ultrasonic echoes reflected by said predetermined object, modulating light in accordance with the ultrasonic echoes and detecting the light to generate data and store the generated data as check data when performance of said ultrasonic diagnostic apparatus is checked;
(c) generating comparison data on the basis of both the management data stored at step (a) and the check data stored at step (b); and
(d) displaying an image on the basis of the comparison data generated at step (c). - View Dependent Claims (7, 8, 9, 10, 11, 12)
