PROBLEM TO BE SOLVED: To facilitate measurement of a body fat percentage of a subject while reducing an exposure dosage on the subject in a body fat percentage measuring apparatus, a method, and a program.SOLUTION: A subtraction processing part 32 generates a soft part image Gs representing a soft tissue of a subject H from first and second radiation images G1, G2. A body thickness estimating part 33 estimates a body thickness distribution of the subject H based on photography conditions in acquiring the soft part image Gs, the first radiation image G1, and the second radiation image G2. An approximation body thickness distribution calculating part 34 calculates an approximation body thickness distribution obtained by approximating the estimated body thickness distribution by a model corresponding to a human body, and a body fat percentage calculating part 35 calculates a distribution of the body fat percentage within the subject H based on the approximation body thickness distribution.SELECTED DRAWING: Figure 1 【課題】体脂肪率測定装置、方法およびプログラムにおいて、被写体への被曝量を低減しつつ、被写体の体脂肪率を簡易に測定できるようにする。【解決手段】サブトラクション処理部３２が、第１および第２の放射線画像Ｇ１，Ｇ２から被写体Ｈの軟部組織を表す軟部画像Ｇｓを生成する。体厚推定部３３が、軟部画像Ｇｓ、第１の放射線画像Ｇ１、および第２の放射線画像Ｇ２を取得した際の撮影条件に基づいて、被写体Ｈの体厚分布を推定する。近似体厚分布算出部３４が、推定した体厚分布を人体に対応するモデルで近似した近似体厚分布を算出し、体脂肪率算出部３５が、近似体厚分布に基づいて、被写体Ｈ内の体脂肪率の分布を算出する。【選択図】図１
