Abstract: Provided is an apparatus for processing a magnetic resonance (MR) image, including: an image acquisition unit configured to acquire a plurality of MR images by performing MR imaging on a moving object during temporally consecutive time intervals; a controller configured to sequentially compare two adjacent MR images from among the plurality of MR images to thereby detect an interval during which motion occurs; an image processor configured to calculate a transformation matrix for performing motion correction on at least one MR image corresponding to the detected interval and obtain a motion-corrected MR image by applying the transformation matrix to the at least one MR image; and an output unit configured to display the motion-corrected MR image.
Abstract translation: 提供了一种用于处理磁共振（MR）图像的设备，包括：图像获取单元，被配置为通过在时间上连续的时间间隔内对移动物体执行MR成像来获取多个MR图像; 控制器，被配置为顺序地比较所述多个MR图像中的两个相邻MR图像，从而检测发生运动的间隔; 图像处理器，其被配置为计算用于对与所述检测到的间隔相对应的至少一个MR图像执行运动校正的变换矩阵，并通过将所述变换矩阵应用于所述至少一个MR图像来获得运动校正的MR图像; 以及输出单元，被配置为显示运动校正的MR图像。

Abstract: A magnetic resonance imaging (MRI) apparatus and a method of processing an MR image are provided. The MRI apparatus includes a scanner configured to acquire a first image that is a T1-weighted image and a second image that is a fluid attenuated inversion recovery (FLAIR) image by performing an MRI scan on a brain. The MRI apparatus further includes an image processor configured to determine a white matter region in the second image based on the first image and the second image, and detect a white matter hyperintensity (WMH) region in the determined white matter region. The MRI apparatus further includes an output interface configured to display the detected WMH region and a change in the WMH region over time.
