The Diffusion Weighted Imaging (DWI) reconstruction of tomograms with different time sequence parameters were considered. For the respective time parameters the sensitivity to diffusion weighting is found. Full reconstructed tomograms and fragments weighted with sensitivity parameters have been obtained. The reconstructed tomograms were weighted to sensitivity parameters filtered with the Gaussian matrix. The optimal sensitivity parameters for the DWI reconstruction have been proposed.

The physical model of cell ratio object is used for calculation of additional magnetic fields caused by the interaction of magnatic moments. There have been calculated the additional magnetic fields caused by the interaction of magnetic moments. The spatial density reconstruction of the modeled object with additional magnetic fields was obtained by MRI. The pseudo-inversion matrix method is used for spatial density reconstruction of investigated object. The calculation of additional magnetic fields while reconstruction of small objects gives more precise and full information about investigated objects.
