PROBLEM TO BE SOLVED: To reduce the capacity of a delay quantity adjustment memory used in an ultrasonic beam forming apparatus.SOLUTION: The delay adjustment memory is shared between two signal processing channels. A signal in on signal processing channel with a smaller delay time is adjusted in delay by the delay adjustment memory, and a signal in the other signal processing channel with a larger delay time is directly input in a subsequent calculation part without passing through the delay adjustment memory, thereby the ultrasonic receiving beam forming process is performed.COPYRIGHT: (C)2010,JPO&INPIT【課題】超音波ビーム成形装置にて用いられる遅延量調整メモリの容量を低減させる。【解決手段】遅延調整メモリを2つの信号処理経路間で共有し、遅延時間の早い信号処理経路の信号を遅延調整メモリにて遅延調整し、遅延時間の遅い方の信号処理経路の信号を遅延調整メモリを介さず、後段の演算部に直接入力し、超音波受信ビーム成形処理を行う。【選択図】図1
