Abstract

Patient motion can significantly hamper the high-resolution imaging capability of PET scanners. Frame-acquired (dynamic) PET images are degraded by inter-frame and intra-frame motion artifacts that can degrade the quantitative and qualitative analysis of acquired PET data. This calls for appropriate motion-correction techniques that can considerably reduce (ideally eliminate) inter-frame and intra-frame motion artifacts in dynamic PET images.
