Ellipsoid mapping of the breast with a specific colorization mode has been developed as a visualization means for evaluating the entire information embedded in breast Diffusion Tensor Imaging (DTI) and improve breast cancer detection. The 3D ellipsoid maps were displayed at voxel resolution with their shape and orientation determined by a respective eigenvalue-eigenvector pair of the associated diffusion tensor, followed by colorizing the ellipsoids according to the values of each diffusion tensor parameter. The results show that the enhanced ellipsoid mapping with λ1 colorization accentuating breast malignancy, may allow efficient differentiation of breast malignancy from normal breast tissue.
