The present invention provides technology for evaluating a nuclear medicine image of a head that is not easily influenced by differences in set reference areas. In general, an embodiment of the present invention includes the setting of a reference area in an area of a head nuclear medicine image corresponding to a scalp, the calculation of information relating to pixel values of the set reference area, and the use of the information to normalize and output the pixel values of each pixel included in the head nuclear medicine image or values determined from the pixel values.本發明提供一種頭部核醫學圖像的評價技術,其為不易因參照區域的設定不同而受到影響之技術。一般來說,本發明的實施形態具有下列步驟:在頭部核醫學圖像中的對應頭皮的區域中設定參照區域;計算與前述所設定之參照區域的像素值有關之資訊;以及利用前述資訊,將包含在前述頭部核醫學圖像中的各像素的像素值或從該像素值求得之值,進行正規化並輸出。100‧‧‧系統102‧‧‧CPU104‧‧‧主儲存裝置106‧‧‧輔助儲存裝置107‧‧‧顯示器介面108‧‧‧周邊機器介面109‧‧‧網路介面110‧‧‧OS120‧‧‧頭部核醫學圖像解析程式122‧‧‧參照區域設定模組124‧‧‧評價資訊製作輸出模組130‧‧‧頭部核醫學圖像(功能圖像)132‧‧‧形態圖像134、136‧‧‧資料
