Zusammenfassung: | To enable a user to intuitively grasp an influence on an ultrasonic image caused by lowering in sensitivity of an element included in an ultrasonic probe.SOLUTION: An ultrasonic observation device 3 comprises: a determination unit 35 which determines whether each of a plurality of elements is a sensitivity-lowered element having a lowered sensitivity by using data of a digital signal corresponding to an echo signal received by each of the elements; an area identifying unit 36 for identifying a sensitivity-lowered area in an ultrasonic image on the basis of a contribution degree, on an ultrasonic beam, of the element determined to be the sensitivity-lowering element by the determination unit 35; and a sensitivity-lowered-part-displaying-image generating unit 37 for generating data on a sensitivity-lowered-part-displaying image for displaying the area identified by the area identifying unit 36.SELECTED DRAWING: Figure 1
【課題】超音波プローブが有する素子の感度低下に起因した超音波画像への影響を、ユーザが直観的に把握することを可能にする。【解決手段】超音波観測装置3は、複数の素子がそれぞれ受信するエコー信号に対応するデジタル信号のデータを用いて各素子が感度低下を有する感度低下素子であるか否かを判定する判定部35と、判定部35が感度低下素子であると判定した素子の超音波ビームに対する寄与度をもとに超音波画像中において感度が低下した領域を特定する領域特定部36と、領域特定部36が特定した領域を表示する感度低下部表示画像のデータを生成する感度低下部表示画像生成部37と、を備えた。【選択図】図1 |
