PROBLEM TO BE SOLVED: To provide an acoustic wave acquisition device in which a probe hardly takes an unstable posture even when a relatively near position is specified as a measurement value, in a device that an operator specifies a measurement position.SOLUTION: An acoustic wave acquisition device moves a probe so that a ratio of a length of a trajectory to a distance between a first point and a second point becomes large when a distance between the probe positioned at the first point and the second point corresponding to a target position goes below a prescribed threshold relative to when exceeds the prescribed threshold.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】操作者が測定位置を指定する装置において、比較的近い位置を測定値と指定された場合にも、探触子の姿勢が不安定になりにくい音響波取得装置を提供する。【解決手段】第1の点にある探触子と目標位置に対応する第2の点との間の距離が所定の閾値を上回る場合よりも、閾値を下回る場合の方が、第1の点と第2の点との距離に対する軌道の長さの比が大きくなるように、探触子を移動させる。【選択図】図5
