ABSTRACT:
Delay time data for using the transducers arranged within a probe, for transmitting and receiving an ultrasonic beam, is stored in a memory. The amount of this delay time data is less than that required for using all transducers. The delay time data stored in the memory is interpolation-processed, thereby providing additional delay time data. The sum of the delay time data stored in the memory and the additional delay time data obtained by the interpolation-processing suffices to use all the transducers incorporated in the probe.
