PROBLEM TO BE SOLVED: To reduce acquisition of input signals that does not significantly contribute to acquiring subject information in a high resolution manner.SOLUTION: The subject information acquisition device includes: a holding member with an opening into which a subject part that is part of a subject is inserted and an opening regulation member for regulating a shape of the opening. A movement area of a support body for supporting a transducer is defined based on the shape of the opening.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 被検体情報を高分解能に取得するために大きく寄与しない受信信号の取得を低減する。【解決手段】 被検体情報取得装置は、被検体の一部である被検部を挿入するための開口を備える保持部材と、開口の形状を規定する開口規定部と、を有し、開口の形状に基づいて、トランスデューサを支持する支持体の移動領域を決定する。【選択図】 図1
