Abstract
A radiation applicator system is structured to be mounted to a radiation source for providing a predefined dose of radiation for treating a localized volume of tissue, such as the tissue surrounding the site of an excised tumor. The applicator system includes an applicator and, in some embodiments, an adapter. The adapter is formed for fixedly securing the applicator to a radiation source, such as a radiosurgery system which produces a predefined radiation dose profile with respect to a predefined location along its radiation producing probe. The applicator includes a shank and an end cap, wherein the end cap includes a substantially flat or convex treatment surface and is located at a distal end of the applicator shank. A proximate end of the applicator shank couples to the adapter. A distal end of the shank includes the end cap, which is adapted for engaging and preferably supporting the area to be treated with a predefined does of radiation. The applicator can include a low energy radiation filter inside of the applicator end cap to reduce undesirable low energy radiation emissions. A plurality of applicators having end caps of different sizes and shapes can be provided to accom…
