Real-Time kV Imaging vs. Real-Time 3D Patient Surface Tracking for Head & Neck Cancer

Trial ID or NCT#



not recruiting iconNOT RECRUITING


To determine if a new optical system that can track a patient's movement during treatment can be used to measure motion and allow for motion adjustments in order to decrease the amount of healthy tissue that receives radiation without limiting our ability to cure cancers using radiation.
