PROBLEM TO BE SOLVED: To provide photoacoustic wave probes, etc. capable of acquiring subject information for reducing occurrence of artifacts.SOLUTION: An acoustic wave probe comprises: a support member 103 a plurality of acoustic wave transducers 101 mounted on a support face of the support member and driving means for causing an arrangement pattern P of receivable areas of the acoustic wave transducers viewing from a direction intersecting the support face, to reciprocate within a predetermined range. The arrangement pattern P is divided into a plurality of regions along the direction of movement, the receivable areas of the acoustic wave transducers being arranged in each of the plurality of regions in the same pattern when viewed from the intersecting direction. The same pattern includes the pattern of the receivable areas of the plurality of acoustic wave transducers arranged in a direction intersecting the direction of movement, when viewed from the intersecting direction.SELECTED DRAWING: Figure 2-1COPYRIGHT: (C)2017,JPO&INPIT【課題】アーチファクトの発生を低減するための被検体情報を取得できる光音響波プローブ等を提供する。【解決手段】支持部材103と、支持部材の支持面に設けられた複数の音響波トランスデューサ101と、支持面と交差する方向から見る音響波トランスデューサの受信可能領域の配置パターンPを所定の範囲で往復移動させる駆動手段を有する。配置パターンPは、前記移動の方向に沿って複数の領域に別けられ、複数の領域のそれぞれで音響波トランスデューサの受信可能領域は前記交差する方向から見て同じパターンで配置される。同じパターンは、前記交差する方向から見て前記移動の方向と交差する方向に配列された複数の音響波トランスデューサの受信可能領域のパターンを含む。【選択図】 図2-1
