Abstract
State of the art PET-MR systems are capable of performing both PET and MR measurements simultaneously. However, the resulting data sets are usually processed in two separate reconstruction pipelines. The goal of this work is to complement simultaneous data acquisition with a new multi-modality reconstruction framework based on second order total generalized variation that simultaneously reconstructs both PET and MR images. Information of the underlying anatomy is shared during the image reconstruction process with a dedicated multi-channel regularization functional. Results of numerical simulations and in-vivo data are presented that demonstrate improved PET resolution and reduced noise in MR in comparison to conventional reconstructions.
