Self-gated MRI motion modeling for respiratory motion compensation in integrated PET/MRI
MRI-based compensation of respiratory motion for PET in integrated PET/MRI systems. Motion modeling with the help of a stack-of-stars MRI pulse sequence and self-gating. Extensive experiments: minimal number of respiratory bins, required scan time. Ungated, gated and motion-compensated reconstructions in 15 oncological patients. Motion compensation yields high lesion sharpness without SNR loss.
