PROBLEM TO BE SOLVED: To provide a technology capable of easily optimizing compression conditions when a subject is compressed and held at the time of measuring a photoacoustic wave.SOLUTION: A subject information acquisition device having a plurality of members which compress and hold a subject for generating characteristic information in the subject based on an acoustic wave transmitted from the subject irradiated with light includes: a means for acquiring a first compression condition which is a reference value at the time of compressing the subject a means for acquiring a second compression condition for representing a state in which the subject is compressed by the plurality of members and an output means for outputting the information based on the first compression condition and the second compression condition.COPYRIGHT: (C)2013,JPO&INPIT【課題】光音響測定時に被検体を圧迫保持する際、圧迫条件を容易に適正化するための技術を提供する。【解決手段】被検体を圧迫して保持する複数の部材を有し、光を照射された被検体から伝搬する音響波に基づいて被検体内の特性情報を生成する被検体情報取得装置であって、被検体を圧迫する際の基準値である第一の圧迫条件を取得する手段と、複数の部材により被検体が圧迫されている状態を示す第二の圧迫条件を取得する手段と、第一の圧迫条件および第二の圧迫条件に基づく情報を出力する出力手段を有する被検体情報取得装置を用いる。【選択図】図1
