PROBLEM TO BE SOLVED: To appropriately diagnose an object to be diagnosed noninvasively by acquiring, on the basis of elastic information measured by a medical image apparatus, a specific diagnosis evaluation value for evaluating whether a diagnosis region is benign or malignant.SOLUTION: The medical image apparatus includes: an elastic information computing part 32 for computing the elastic image information on the basis of tomographic image information of the diagnosis region of a subject photographed through times a hardness-ratio computing part 64 for acquiring the hardness ratio, that is a ratio between an elastic value of a first region and an elastic value of a second region set within the diagnosis region, on the basis of the elastic image information a diagnosis-evaluation-value calculating part 65 for calculating a diagnosis evaluation value corresponding to the hardness ratio, which is acquired by the hardness-ratio computing part, on the basis of the preset correlation between the hardness ratio and the diagnosis evaluation value and an image display part on which the elastic image formed on the basis of the elastic image information and a diagnosis evaluation value acquired by the diagnosis-evaluation-value calculating part are displayed.COPYRIGHT: (C)2013,JPO&INPIT【課題】医用画像装置により計測される弾性情報に基づいて、診断部位の良悪性を評価する特有の診断評価値を求め、非侵襲で診断対象の診断を適切に行う。【解決手段】時系列的に撮像される被検体の診断部位の断層像情報に基づいて弾性像情報を演算する弾性情報演算部32と、弾性像情報に基づいて、診断部位に設定される第1の部位の弾性値と第2の部位の弾性値の比である硬度比を求める硬度比演算部64と、硬度比演算部で求めた硬度比に対応する診断評価値を、予め設定された硬度比と診断評価値との相関関係に基づいて算出する診断評価値算出部65と、弾性像情報に基づいて作成される弾性像と、診断評価値算出部で求めた診断評価値を表示する画像表示部を備える。【選択図】図2
