Abstract
A radiation applicator system is structured to be mounted to a radiation source for producing a beam of radiation for treating a localized volume of tissue, such as growing blood vessels in the eye that can cause macular degeneration. 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 the radiation producing probe. The applicator includes a shank and an applicator head. A proximate end of the applicator shank couples to the adapter. A distal end of the shank includes the applicator head, which is adapted to produce a beam of radiation. The applicator head includes a radiation shield and a beam collimator. The radiation shield selectively blocks the emitted radiation so that the applicator can be held by a surgeon during treatment. The beam collimator extends from an aperture in the shield that forms and directs a beam of radiation at a target area. Applicator systems that form different size and shape beams of radiation can be provided to accommodate a wide range of treatment volumes and for use in different treatments.
