1. A magnetic resonance imaging system, comprising:

  • at least one processor programmed to;

    receive diffusion weighted imaging data from a region of interest of a subject based on a diffusion weighted imaging sequence with magnetic gradient fields applied in different directions and with different b-values;

    detect motion corrupted data present in the received imaging data based on a comparison of data redundant in the received data, the data redundancy existing from the diffusion weighted imaging data received for the magnetic gradient fields applied in three orthogonal directions, the motion corrupted data being detected by comparing the diffusion weighted imaging data from two of the three orthogonal directions with the diffusion weighted imaging data from a third orthogonal gradient field measure of a third of the three orthogonal directions; and

    substitute alternative data for detected motion corrupted data.
