1. A magnetic resonance imaging (MRI) apparatus comprising:

  • an image display device configured to display a plurality of diffusion weighted images of respective axes corresponding to one slice;

    a designation operating device configured to enable an operator to designate each diffusion weighted image targeted for rephotograph from the displayed diffusion weighted images;

    a diffusion weighted imaging device configured to rephotograph only the axis of each diffusion weighted image designated by the operator to generate a rephotographed diffusion weighted image;

    a diffusion weighted image substituting device configured to generate a set of post-substitution diffusion weighted images by substituting each designated diffusion weighted image with each rephotographed diffusion weighted image; and

    a diffusion tensor image creating device configured to create a diffusion tensor image from the set of post-substitution diffusion weighted images.
