description To provide a technique for reducing the effects of body movement when performing photoacoustic imaging using a hand-held ultrasound probe.SOLUTION: The present invention uses a subject information acquisition apparatus which includes a hand-held ultrasound probe 124, a position information detection unit 123, and an image processing unit 119. The hand-held ultrasound probe includes: an optical system for illuminating a subject 113 with measurement light emitted from a light source 101; a transducer 115 for receiving an acoustic wave 114 generated in the subject to output a signal; and an imaging unit 122 for imaging a surface of the subject to capture a texture image. The position information detection unit acquires a relative position between the ultrasound probe and the subject using the texture image captured by the imaging unit. The image processing unit generates three-dimensional volume data indicating characteristic information of the subject using a plurality of signals derived from acoustic waves received at a plurality of positions of the subject and the relative position.SELECTED DRAWING: Figure 1 【課題】ハンドヘルド型超音波探触子を用いて光音響イメージングを行う場合に、被検体の体動の影響を低減する技術を提供する。【解決手段】光源101から発生した測定光を被検体113に照射する光学系と、被検体から発生する音響波114を受信して信号を出力するトランスデューサ115と、被検体の表面を撮像してテクスチャ画像を取得する撮像部122と、を含むハンドヘルド型の超音波探触子124と、撮像部が取得したテクスチャ画像を用いて、超音波探触子と被検体の相対位置を取得する位置情報検出部123と、被検体の複数の位置で受信された音響波に由来する複数の信号と、相対位置とを用いて、被検体の特性情報を示す3次元ボリュームデータを生成する画像処理部119を有する被検体情報取得装置を用いる。【選択図】図1
