Diffusion weighted imaging (DWI) acquisitions typically
suffer from a lower spatial resolution, compared to
their T1 structural counterparts, but provide unique
angular information. Researchers and clinical users may
often find themselves switching back and forth between
the "traditional" directionally-encoded colour (DEC) FA
map and a T1 map to navigate anatomy, or try to overlay
them using (partial) transparency. We propose a
panchromatic sharpening approach tailored to (FOD-based)
DEC and (T1) structural information to create a single
fused image. The resulting contrast is striking and
allows for easy identification of various anatomical
structures beyond the resolution of the DWI data.
