PROBLEM TO BE SOLVED: To reduce an overflow amount of acoustic matching liquid from a liquid tank, and suppress lowering of a liquid level of the acoustic matching liquid in a device for acquiring an acoustic wave.SOLUTION: An acoustic wave reception device includes: a support base for supporting a subject, to which an opening is provided a holding member fixed to the support base in the periphery of the opening for holding a subject which is a part of a person to be examined inserted from the opening a liquid tank located below the support base and the holding member, in which an acoustic probe for receiving an acoustic wave propagating from the subject through the holding member is disposed, and acoustic matching liquid is stored to a liquid level that the holding member and the acoustic probe are acoustically connected a scanning part for moving the acoustic probe at least in a horizontal direction with respect to the opening and a float which is floated on the acoustic matching liquid, and surrounds the holding member on a liquid surface of the acoustic matching liquid.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】音響波を取得する装置において、液槽からの音響整合液の溢れ量を低減し、音響整合液の液位低下を抑制する。【解決手段】被検者を支持するとともに、開口が設けられた支持台と、開口の周辺において支持台に固定され、開口から挿入された被検者の一部である被検体を保持する保持部材と、支持台および保持部材の下方に位置し、保持部材を介して被検体から伝搬する音響波を受信する音響プローブが配置され、保持部材と音響プローブが音響的に結合する液位まで音響整合液が貯留される液槽と、音響プローブを、開口に対して少なくとも水平方向に移動させる走査部と、音響整合液に浮かべられ、音響整合液の液面において保持部材を囲むフロートを有する音響波受信装置を用いる。【選択図】図1
