On-treatment Adaptation of Head and Neck Cancer Dosimetry Plans Using Novel Cone-beam CT and AI-driven Software

Subjects are scheduled for two imaging sessions on the Ethos system with the HyperSight CBCT. One session is on the same day as the CT simulation scan for treatment planning. The second session is on the same day as the delivery of ther 21st treatment fraction. If the subject is sent for a mid-treatment FBCT for re-planning, a third HyperSight CBCT imaging session will be scheduled on the same day as the mid-treatment FBCT.
