Digital Brain Perfusion Phantom
The Digital Brain Perfusion Phantom package provides data and Matlab tools to create a realistic digital 4D brain phantom, in particular for reproducible evaluation of reconstruction algorithms using non-linear regularization for perfusion CT and perfusion C-arm CT. It is based on the Realistic Digital Brain Perfusion Phantom originally published by Riordan et al. Since classical digital CT phantoms usually consist of homogeneous structures and have very sparse representation in transformations like total variation or wavelets, they highly favor non-linear reconstruction algorithms. This phantom allows for a more authentic evaluation by providing a brain model based on real physiological data and avoiding sparsity by continuously varying perfusion parameters and anatomical structures using MR data.
