Multi-modality imaging combines morphological and functional information originating from different imaging platforms and is based on the critical assumption of accurate registration. In the presented work a tri-modality PET/CT+MR system is used to investigate the hardware registration performance between sequential PET and MR versus gold standard PET/CT.
