Collection of Head Images During Radiotherapy

The primary objective of this observational study is to quantify the translation, rotation, and deformation of patient head positions of head and neck cancer patients over the course of a radiation therapy treatment for head and neck cancer. This objective will be achieved by comparing X-ray images collected during each treatment session with those obtained from the planning CT scan. Secondary objectives include (1) the use of the collected X-ray images to develop realistic artificial X-ray images where patient movement can be simulated and (2) to determine whether motion can be detected from individual X-ray images acquired during radiation therapy treatment.
