Joint MR-PET Reconstruction Using a Multi-Channel Image Regularizer.
IEEE Transactions on Medical Imaging(2017)
摘要
While current state of the art MR-PET scanners enable simultaneous MR and PET measurements, the acquired data sets are still usually reconstructed separately. We propose a new multi-modality reconstruction framework using second order Total Generalized Variation (TGV) as a dedicated multi-channel regularization functional that jointly reconstructs images from both modalities. In this way, informat...
