摘要：
According to an embodiment of the present invention, provided are a medical imaging apparatus and method for estimating tensor through motion compensation. According to an embodiment of the present invention, the medical imaging apparatus for estimating tensor through motion compensation comprises: a coil unit configured to form a diffusion-weighted gradient magnetic field corresponding to each of a plurality of directions in a target part of an object； an image processing unit corresponding to each direction by the diffusion-weighted gradient magnetic field formed through the coil unit, and obtaining a plurality of slice images of the target part； and a processor configured to generate a diffusion-weighted image corresponding to each direction by sequentially combining the obtained slice images. The processor generates a simulated diffusion-weighted image by matching a reference image, which is not diffusion weighted, with the diffusion-weighted image corresponding to each direction, matches a plurality of slice images constituting the simulated diffusion-weighted image with a plurality of slice images of the diffusion-weighted image corresponding to each direction, corrects a direction vector for each slice image of the diffusion-weighted image corresponding to the direction when each slice is measured by matching with the simulated diffusion-weighted image, estimates a diffusion tensor for each slice image by using the corrected direction vector for each slice image of the diffusion-weighted image corresponding to each direction, and generates a diffusion tensor image by using the corrected direction vector and an estimated diffusion tensor for each slice image of the diffusion-weighted image corresponding to each direction. The present invention can obtain an accurate diffusion tensor image, thereby being able to accurately and precisely diagnose disease.COPYRIGHT KIPO 2020본 발명의 실시예에 따른 움직임 보정을 통해 텐서 추정을 위한 의료 영상 장치 및 방법이 제공된다. 본 발명의 실시예에 따른 움직임 보정을 통해 텐서 추정을 위한
