  • Abstract
    The authors describe the techniques for measuring diffusion coefficients and creating DWI and DTI images. In order to increase the accuracy of diffusion coefficient measurement, it is necessary to eliminate the influence of artifacts such as the influence of magnetic field inhomogeneity, eddy currents, or temperature. For these artifact sources, the article presents experimental detection of the magnitude of errors, which is realized using the three measurements method, and proposes correction possibilities. The results are compared with diffusion measurements at different sizes of 6-factors.
