Abstract:
1. A method for correcting distortions in image data in diffusion imaging in magnetic resonance tomography, comprising the steps of: acquiring image data with an imaging magnetic resonance tomography scan for a predetermined diffusion weighting, and image data mapping a predetermined image segment; supplying said image data to a computerized processor, and in said computerized processor, determining a diffusion model for said image segment; in said processor, determining output image data for said image segment that are substantially free of distortions caused by diffusion weighting associated said diffusion model; estimating reference image data for said predetermined diffusion weighting for said image segment based on said output image data and said diffusion model; in said processor, comparing the acquired image data with said reference image data to obtain a comparison result; and in said processor, using said comparison result to correct distortions in said acquired image data.
