PROBLEM TO BE SOLVED: To support a diagnosis by comparing three-dimensional imaging data of a subject with those of a comparison subject per unit of a region of interest.SOLUTION: This diagnosis system includes: storage sections 11 and 13 storing three-dimensional imaging data acquired by capturing the brains of a subject and a plurality of healthy subjects a storage section 17 storing VOI data in the brains, predetermined according to diseases a healthy subjects VOI processing section 19 referring to the storage sections 13 and 17 to specify first representative values representing VOIs in each of the plurality of healthy subject data 131 for every healthy subject data 131 a subjects VOI processing section 21 referring to the storage sections 11 and 17 to specify a second representative value representing the VOI in the standard brain data 113 of the subject and a Z value calculation section 23 evaluating the second representative value on the basis of the plurality of first representative values for every healthy subject data 131.COPYRIGHT: (C)2011,JPO&INPIT【課題】関心領域単位で被験者と比較対象者の3次元撮像データとを比較して、診断を支援する。【解決手段】被験者、及び複数の健常者の脳を撮像した3次元の撮像データを記憶する記憶部11,13と、脳における、疾患別に予め定められているVOIデータを記憶する記憶部17と、記憶部13,17を参照して、複数の健常者データ131のそれぞれにおけるVOIを代表する第一の代表値を、健常者データ131ごとに特定する健常者VOI処理部19と、記憶部11,17を参照して、被験者の標準脳データ113におけるVOIを代表する第二の代表値を特定する被験者VOI処理部21と、健常者データ131ごとの複数の第一の代表値に基づいて、第二の代表値を評価するZ値算出部23とを備える。【選択図】図1
