摘要：
Simultaneous magnetic resonance imaging (MRI) and positron emission tomography (PET) enable simultaneous acquisition of anatomical and functional imaging. Currently, separate reconstruction of MRI and PET images is performed. Recently, joint reconstruction of MRI-PET has been explored using gradient based priors, which have the risk of infusing cross-modality artefacts. We propose a coupled MR-PET patch based dictionary prior for the joint reconstruction of MRI and PET contrasts.
