Abstract: A system of generating data from diffusion-weighted images for pre-processing and a method thereof are disclosed. In the system, a processing parameter set including diffusion information is acquired; after a raw diffusion-weighted image including data images and image information is acquired, the image information is interpreted to set image processing data of the raw diffusion-weighted image, and non-deformation correction and deformation correction are performed on the raw diffusion-weighted image to generate a pre-processed diffusion-weighted image based on the processing parameter set and the image processing data. Therefore, the image processing data can be automatically set based on the raw diffusion-weighted image, to achieve the effect of lowering difficulty for analyzing DWI and saving setup time of image processing data.
