PROBLEM TO BE SOLVED: To provide a technique for performing excellent imaging in an acoustic wave reception device which performs photoacoustic imaging and ultrasonic echo imaging.SOLUTION: An acoustic wave reception device comprises: a light irradiation unit which irradiates a target region with light a reception array made by arranging a plurality of reception elements which receive photoacoustic wave caused by the light irradiation to output a photoacoustic signal a transmission/reception array made by arranging a plurality of transceiver elements which transmit a supersonic wave to the target region and receive echo of the supersonic wave reflected by the target region to output an ultrasonic signal and an array support part including a support area in which a reception array is supported so that oriented axes of a plurality of reception elements go toward an effective reception area and the transmission/reception array. A convergence area formed by the transmission/reception array is overlapped with the effective reception area.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】光音響撮像および超音波エコー撮像を行う音響波受信装置において、良好な撮像を行うための技術を提供する。【解決手段】被検部に光を照射する光照射部と、光照射により発生する光音響波を受信して、光音響信号を出力する複数の受信素子が配列された受信アレイと、超音波を被検部に送信し、超音波が被検部で反射されたエコーを受信して超音波信号を出力する複数の送受信素子が配列された送受信アレイと、受信アレイを、複数の受信素子の指向軸が有効受信領域と送受信アレイに向かうように支持される支持領域を有するアレイ支持部とを有し、送受信アレイにより形成される集束領域と有効受信領域が重なる音響波受信装置を用いる。【選択図】図1
