Abstract
A phased-array receiver used in an ultrasonic diagnostic apparatus or the like for appropriately varying the phases of the output voltages from transducer elements receiving ultrasonic waves and for summing these voltages to change the directional or other characteristics of ultrasonic waves. The receiver is equipped with a plurality of blocks each comprising a tapped delay line and a crosspoint switch. The crosspoint switch is capable of selecting any desired one of various delay periods of the delay line. The receiver can perform all types of scans ranging from linear scan, intermediate scan, dynamic focusing scan, to sector scan.
