PROBLEM TO BE SOLVED: To prevent reduction in an adaptive beamforming effect even when a signal cannot be received correctly by part of an element.SOLUTION: An ultrasonic measurement device includes: a reception processing part which receives an ultrasonic echo of an ultrasonic wave transmitted to an object via an ultrasonic element array having a plurality of channels as a reception signal for each channel an error detection part which detects an error for each channel a signal processing part which performs weighted addition of a reception signal for each normal channel other than an error channel in which the error is detected with weight in accordance with the reception signal for each normal channel and an image generation part which generates an image on the basis of the signal subjected to the weighted addition.COPYRIGHT: (C)2015,JPO&INPIT【課題】素子の一部で信号を正しく受信できない場合でも、適応型ビームフォーミングの効果の低下を防ぐ。【解決手段】超音波測定装置は、対象物に対して送信された超音波についての超音波エコーを、複数のチャンネルを有する超音波素子アレイを介して前記チャンネル毎の受信信号として受信する受信処理部と、前記チャンネル毎にエラーを検出するエラー検出部と、前記エラーが検出されたエラーチャンネル以外の正常チャンネル毎の受信信号を、前記正常チャンネル毎の受信信号に応じた重みで、重み付き加算する信号処理部と、前記重み付き加算が行われた信号に基づいて画像を生成する画像生成部と、を有する。【選択図】図5
