Improved immobilization using an individual head support in head and neck cancer patients.
The benefits of a patient-specific head support, developed to improve immobilization during radiotherapy, were determined in head and neck cancer patients. Cone-beam CTs were registered to the planning CT in five regions. Compared to the standard head support, the individual head support decreased the systematic and random errors of the inter- and intrafraction displacements and reduced deformations.
