First Claim
1. A pod for supporting a head and neck region of a patient during radiation treatment, the pod comprising:
- a shell generally conforming to the head and neck region of the patient, the shell comprising a shell caudal end, a cephalad end, and the shell extending upwardly from an inner surface of the shell and around the sides of the patient'"'"'s head forming a channel, the shell tapering to a smaller thickness as the shell extends upwardly from the inner surface of the shell;
a facemask configured to attach to an outer surface of the shell to immobilize the patient, the facemask having a first facemask lateral edge and a second facemask lateral edge and configured to extend laterally in the head and neck region of the patient; and
a facemask-to-shell attachment system comprisinga first pin formed in an outer surface of the shell on one side of the patient'"'"'s heads,a second pin formed on an outer surface of the shell on the other side of the patient'"'"'s,a first receiving slot near the first facemask lateral edge to receive the first pin, anda second receiving slot near the second facemask lateral edge to receive the second pin.

Abstract
Support devices and pods for the head and neck region of patients undergoing radiation therapy are provided herein. The pod generally includes a support shell shaped to generally conform to the shape of the head and neck region of the patient, a foam insert that conforms to the head and neck region of the patient, and an immobilization facemask attached directly to the shell, thereby facilitating close placement of the radiation beam delivery device to the patient and reducing any attenuation and perturbation of radiation doses directed at the patient. The components of the pod are made from materials having properties that reduce any attenuation and perturbation of prescribed radiation doses.

10. A pod for immobilizing a head region of a patient during radiation treatment, the pod comprising:
-
a shell shaped to generally conform to the shape of the head and neck region of the patient, the shell extending longitudinally from a shell caudal end to a cephalad end, the shell extending from a first shell edge to a second shell edge, the shell being configured to extend upwardly from an inner surface of the shell and around the sides of said patient'"'"'s head, the tapering to a smaller thickness as the shell extends upward to terminate at the first and second shell edges, the shell defining a channel between the first shell edge and the second shell edge, a width of the shell at the caudal end being greater than a width of the shell at the cephalad end; a facemask configured to attach to the first shell edge and the second shell edge of the shell in order to immobilize the patient'"'"'s face, the facemask having a first facemask edge and a second facemask edge; and a facemask-to-shell attachment system comprising a first locating pin formed near the a first shell edge, a second locating pin formed near the second shell edge, a first receiving slot near the first facemask edge to receive the first locating pin, and a second receiving slot near the second facemask edge to receive the second locating pin. - View Dependent Claims (11, 12, 13, 14, 15)
