Abstract

The invention discloses a multi-modal magnetic resonance image-based brain gray matter and white matter tracking method and device. The method comprises the following steps: acquiring brain image dataof a sample crowd to obtain a structural magnetic resonance image and a diffusion tensor image; preprocessing the structural magnetic resonance image and the diffusion tensor image to obtain a braingray matter image and a partial anisotropy coefficient image; and fusing the brain gray matter image and the partial anisotropy coefficient image to realize brain gray matter and white matter tracking. According to the invention, a multivariable analysis method is adopted to fuse multi-modal magnetic resonance images (a structural magnetic resonance image and a diffusion tensor image). The problems in the prior art that using a univariate method for analyzing structural magnetic resonance images or diffusion tensor imaging data and other single-mode magnetic resonance data causes some hidden joint information to be ignored. The method and the device for tracking the gray matter and the white matter of the brain are rich in data, comprehensive in analysis and accurate in result.
