PROBLEM TO BE SOLVED: To provide a medical image processing apparatus which is equipped with an adaptability index map generator to generate multiple kinds of adaptability index maps respectively corresponding to multiple kinds of perfusion models, so as to support improving the accuracy of diagnosis by perfusion analysis.SOLUTION: The medical image processing apparatus handles data on a series of medical image relating to a subject. A time-concentration curve generator 121 generates a plurality of time-concentration curves respectively corresponding to a plurality of pixels from the series of medical images. A approximation processor 123 approximate a convolution of a specific time-density curve among the multiple time-concentration curves and the respective perfusion models of the multiple kinds with respect to the respective time-concentration curves of the multiple kinds along with the adjustment of at least one parameter which each of the perfusion models has. The adaptability index map generator 124 generates the multiple kinds of adaptability index maps respectively corresponding to the multiple kinds of perfusion models based on a plurality of approximation errors respectively corresponding to the multiple pixels given by the approximation processor.COPYRIGHT: (C)2012,JPO&INPIT【課題】灌流解析の診断精度向上を支援すること。【解決手段】医用画像処理装置は、被検体に関する一連の医用画像のデータを扱う。時間濃度曲線発生部121は、一連の医用画像から複数の画素にそれぞれ対応する複数の時間濃度曲線を発生する。近似処理部123は、複数の時間濃度曲線中の特定の時間濃度曲線と、複数種類の灌流モデル各々とのコンボリューションを、灌流モデル各々が有する少なくとも一つのパラメータの調整を伴って複数の時間濃度曲線各々に対して近似させる。適合性指標マップ発生部124は、近似処理部による複数の画素にそれぞれ対応する複数の近似誤差に基づいて、複数種類の灌流モデルにそれぞれ対応する複数種類の適合性指標マップを発生する。【選択図】 図1
