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.

Condition Intervention
Head and Neck Cancer Procedure: Radiotherapy Procedure: Align RT

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Comparison of Intrafraction Motion in Patients With Head and Neck Cancer Using Real-Time kV Imaging vs. Real-Time 3D Patient Surface Tracking
