Electronic scanning in ultrasonic imaging using a wedge transducer

The position-dependent resonant frequency of a wedge transducer is used to obtain electronic scanning of an ultrasonic beam by varying the frequency. A theoretical calculation of the resolution using the staircase model is in good agreement with the experiment. The principle has been applied to ultr...
