PROBLEM TO BE SOLVED: To suppress buckling by fluid pressure of matching fluid for a holding member used in an acoustic wave reception device.SOLUTION: An acoustic wave reception device includes a holding member for holding a subject, a probe for receiving an acoustic wave generated from the subject, a fluid tank located below the holding member in which the probe is disposed and which holds probe side matching fluid for acoustically coupling the holding member and the probe, and a fluid level control part for controlling the fluid level of the probe side matching fluid so that the fluid pressure of the probe side matching fluid becomes a value lower than a buckling load, which is a threshold for causing buckling to the holding member using information on the fluid level of the probe side matching fluid.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】音響波受信装置に用いる保持部材に対するマッチング液の液圧による座屈を抑制する。【解決手段】被検体を保持する保持部材と、被検体から発生した音響波を受信する探触子と、保持部材の下方に位置し、探触子が配置される液槽であって、保持部材と探触子を音響的に結合させる探触子側マッチング液を保持する液槽と、探触子側マッチング液の液位に関する情報を用いて、探触子側マッチング液の液圧が保持部材に座屈を起こさせる閾値である座屈荷重より低い値となるように、探触子側マッチング液の液位を制御する、液位制御部を有する音響波受信装置を用いる。【選択図】図1
