Zusammenfassung:To perform luminance correction without impairing sharpness of an image.SOLUTION: A medical image correction method according to one embodiment acquires an MR image, and uses information indicating continuity between pixels in the MR image and information for grouping luminance values in the MR image, to divide the MR image into regions. For each divided region, distribution of signal nonuniformity is calculated, and the MR image is corrected on the basis of the distribution of signal nonuniformity.SELECTED DRAWING: Figure 2 【課題】画像の鮮鋭度を損なわずに輝度補正を行うこと。【解決手段】実施形態に係る医用画像補正方法は、MR画像を取得し、MR画像における画素間の連続性を示す情報、及びMR画像における輝度値を群分けする情報を用いて、MR画像を領域分割し、分割された領域毎に信号不均一性の分布を計算し、信号不均一性の分布に基づいて前記MR画像を補正する。【選択図】図2
