PROBLEM TO BE SOLVED: To obtain a more accurate body fat percentage by a method of obtaining the body fat percentage.SOLUTION: Prescribed sectional images G1, G2 and G3 are prepared for a subject 1, and the ratios Rs1-Rs3 of the region Fs indicating the body fat in the cross section to the area of the region Bs indicating the cross section of the subject are obtained for the respective sectional images G1, G2 and G3. The maximum value among the obtained ratios R21-Rs3 for the respective sectional images G1, G2 and G3 is applied to the correlation between the maximum value of the ratios of the body fat area and the body fat percentages previously obtained for a plurality of different human bodies to obtain the body fat percentage of the subject.COPYRIGHT: (C)2009,JPO&INPIT【課題】体脂肪率取得方法において、より正確な体脂肪率を取得することができるようにする。【解決手段】被検者1について、所定の断面画像G1、G2、G3を用意し、各断面画像G1、G2、G3について、被検者1の断面を示す領域Bsの面積に対するこの断面内の体脂肪を示す領域Fsの面積それぞれの比率Rs1~Rs3を得、各断面画像G1、G2、G3毎に求めた上記比率Rs1~Rs3のうちの最大値を、複数の互いに異なる人体について予め求めておいた体脂肪面積比率の最大値と体脂肪率との相関関係に適用して上記被検者の体脂肪率を取得する。【選択図】図2
