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.
