MR DIFFUSION WEIGHTED METHOD AND SYSTEM PROVIDING MICROSTRUCTURAL INFORMATION OF A BIOLOGICAL TARGET USING SINE CARDINAL (SINC) FUNCTION AND Q-SPACE SAMPLING

A method is adapted for providing microstructural information of a biological target from a plurality of diffusion weighted MR images corresponding to a specific area of the biological target. Each of the diffusion weighted MR images is obtained using a respective q-space sampling vector and is sampled at a plurality of sample points thereof to obtain a group of diffusion weighted MR image data. The diffusion weighted MR image data are processed to obtain a spin distribution function from which the microstructural information of the biological target can be obtained.
