Abstract
There is disclosed an ultrasonic tomography apparatus of electronic scanning type in which an array of ultrasonic transducer elements are excited with desired time delays allotted for the transducer elements thereby to transmit and receive ultrasonic beams at a deflection angle corresponding to the desired time delays, and the received echo signal of the ultrasonic beams is displayed on a CRT display device in a form of a tomograph of a sample to which the ultrasonic beams are directed. The apparatus comprises a memory in which both of first signals representative of the time delays given to the transducer elements in dependence on given deflection angles and signals designating display position in the X- and Y-directions of the CRT are previously stored and read out for producing delays allotted for the transducer elements and displaying the received echo signal on the CRT.
