PROBLEM TO BE SOLVED: To provide a subject information acquisition apparatus and a subject support apparatus which can reproduce the position of the subjects body in plural times of measurement.SOLUTION: A subject information acquisition apparatus includes: subject support means which supports a subject in a prone state on a subject support surface storage means which stores body position information on the position of the body with respect to the subject support surface of the subject in the prone state projection means which projects the stored body position information to the subject support surface light irradiation means which irradiates a part to be tested being a part of the subject with light an acoustic wave probe which receives an acoustic wave generated in the part to be tested due to the light and converts the acoustic wave into an electric signal and data processing means which generates information related to optical characteristics in the part to be tested on the basis of the acquired electric signal.COPYRIGHT: (C)2015,JPO&INPIT【課題】複数回の測定において被検者の体の位置を再現できる被検体情報取得装置、および被検者支持装置を提供する。【解決手段】被検者支持面に伏臥した状態の被検者を支持する被検者支持手段と、伏臥状態にある前記被検者の、前記被検者支持面に対する体の位置に関する情報である体位情報を記憶する記憶手段と、前記記憶した体位情報を前記被検者支持面に投影する投影手段と、前記被検者の一部である被検部に光を照射する光照射手段と、前記光に起因して被検部内で発生した音響波を受信し、電気信号に変換する音響波探触子と、前記取得した電気信号に基づいて、前記被検部内の光学特性に関連した情報を生成するデータ処理手段と、を有することを特徴とする。【選択図】図1
