Many degenerative brain disorders are commonly
associated with specific regions of the brain that are
often off-center and can reside within aliased regions
prior to a SENSE reconstruction. While a conventional
array of rectangular coils may generate the most uniform
magnetic field sensitivities throughout the brain, the
human brain is not symmetric, and such sensitivities may
not be optimal for fcMRI studies in all regions. This
study proposes an approach of using spatial
normalization together with an iterated conditional
modes algorithm to morph an array of rectangular coils
into a geometry that is more optimal for a specific ROI.
