Patent ID: 8523630

Claim:
A system for immobilizing a patient and a breast of the patient for delivery of radiation to the breast of the patient, the system comprising: a support structure configured to support a patient lying in a substantially prone position such that a breast to be treated is located below the patient and above the support structure, the support structure further configured to allow the patient to relax and thereby maintain a stable and consistent position for delivery of radiation; a brassiere comprising a cup and at least one strap configured to be worn by the patient, the cup configured to at least partially contain the breast to be treated; and a breast immobilization device comprising a non-caustic substance configurable to at least partially and dynamically fill the space between the brassiere and the support structure, forming, in negative relief, contours corresponding to at least a portion of the cup having the breast to be treated, the breast immobilization device configurable to be positioned on the support structure generally beneath the patient and supporting the cup and the breast to be treated; wherein the non-caustic substance has a first, more expandable state and a second, less expandable state, the first state allowing the non-caustic substance to be introduced into the space between the cup and the support structure, and the second state allowing the non-caustic substance to generally support and retain the breast and cup, thereby substantially immobilizing the breast for radiation treatment.
