Brain Spill-out (Muller-Gartner)

A simplified Muller-Gartner approach can be applied if the segmentation doesn't provide a good separation between GM and WM. In this case the correction is reduced to a spill-out only correction. A brain segment is created by summing the GM and WM probability masks. The brain segment is then convolved with the PSF, and the PET image divided by the result as described by the equation below.
