PROBLEM TO BE SOLVED: To improve quality of a diagnostic index showing an obese state of a human being.SOLUTION: Cross-sectional images Gu showing at least one cross section on the head side in an abdominal region Hb of a subject H and cross-sectional images Gd showing at least one cross section on the leg side in the abdominal region Hb are used to acquire a dimension ratio Pud of a subcutaneous fat region and a dimension ratio Oud of a visceral fat region in regions mutually opposing in the abdominal region Hb. The diagnostic index showing the obese state of the subject H is acquired by comparing two kinds of ratios Pud, Oud with a predetermined reference value.COPYRIGHT: (C)2009,JPO&INPIT【課題】人の肥満の状態を示す診断指標の品質を向上させる。【解決手段】被験者Hの腹部領域Hb中における頭部側の1つ以上の断面を示す断面画像Guと腹部領域Hb中の脚部側の1つ以上の断面を示す断面画像Gdを用いて、腹部領域Hb中の互に対向する部位間における皮下脂肪領域の大きさの比率Pud、および内臓脂肪領域の大きさの比率Oudを求め、2種類の比率Pud、Oudを予め定められた基準値と比較して、前記被験者Hの肥満の状態を示す診断指標を取得する。【選択図】図2
