With the combination of Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) into a single combined system, a novel imaging modality has become available. Previous approaches to patient motion tracking for PET data correction are difficult to use in the combined MR-PET environment. Thus, alternative methods for motion tracking have to be developed. Here, a novel approach for MR-PET motion correction utilising the Lissajous navigator is presented.
