Previous Next 2 of 6 Immobilizing your head

Another type of immobilization device used during radiation therapy is a thermoplastic mask. This mask might be used if you're receiving radiation to your head or neck. The firm plastic mask is molded to your face and secured to the table, so it gently holds your head in place. Some masks may extend to cover your shoulders, as well.
