The
supertoroid-based representation enhances the three-dimensional perception of
biological tissue structure and organization using DT-MRI. The presence of
two additional free parameters in the supertoroidal function allows the
tuning of the glyph surface in order to highlight different structural
properties. Alternatively, these parameters can be used to fuse the
visualization of structure with complimentary information provided by other
modalities. In this work, we combined DT-MRI, MMP-targeted 99mTc-labeled
radiotracer (RP805) uptake, and 201Tl perfusion on a porcine heart
at 2-weeks post-MI, showing that the supertoroidal model can fuse information
arising from different modalities into a unique and comprehensive
visualization scheme.
