Joint reconstruction of PET and MRI is aimed to improve both PET and MR image quality using information from each other’s imaging modality. However, the aim cannot be achieved without correcting the attenuation of PET. We proposed a method to correct attenuation during the process of simultaneous PET and MRI images reconstruction. This method integrates PET, MRI and TOF information.
