PROBLEM TO BE SOLVED: To provide a subject information acquiring apparatus capable of correcting the intensity of subject information relative to each position in the subject on the basis of the resolution for each position in the subject due to the subject information acquiring apparatus.SOLUTION: To solve the problem, the subject information acquiring apparatus 100 according to the present invention irradiates a subject 15 with pulsed light 12 and receives and analyzes a photoacoustic wave 16, which is generated inside a subject due to the pulsed light 12, to capture an image of the subject information. The subject information acquiring apparatus 100 corrects the intensity unevenness in the distribution of absorption coefficients, with consideration given to the difference of resolution due to the position of the subject information acquiring apparatus 100 in the measurement area.COPYRIGHT: (C)2015,JPO&INPIT【課題】被検体情報取得装置に起因する被検体の各位置に応じた解像度に基づいて被検体の各位置での被検体情報の強度を補正できる被検体情報取得装置を提供する。【解決手段】課題を解決するために、本発明に係る被検体情報取得装置100は、パルス光12を被検体15に照射し、パルス光12に起因して被検体15から発生した光音響波16を受信して解析することにより被検体情報を画像化するものであって被検体情報取得装置100の測定エリア内の位置による解像度の違いを考慮した吸収係数分布の強度ムラの補正を行う。【選択図】図1
