Tumor motion leads to bigger margin definition in RT planning causing side effects to patients while diminishing treatment efficacy.
Without MotionFreeIrradiated volume = 33.1cc
With MotionFree
Irradiated volume = 15.6cc
GE MotionFree for Quantification Accuracy generates in particular phase-matched attenuation maps for better quantitative accuracy and tumor contouring therefore improved RT planning and patient outcome. It is achieved by respiratory gating PET and CT scans and correcting for attenuation each PET phase by the corresponding CT phase.
This solution will increase your performance while broadening the scope of your clinical PET activity towards radiotherapists and oncologists.
