RADIATION SYSTEM WITH EMANATING SOURCE SURROUNDING AN INTERNAL ATTENUATION COMPONENT

摘要

Methods and radiation systems for delivery of radiation to a target such as the posterior portion of the eye featuring emanating sources with attenuation materials disposed therein. The emanating sources may be in the shape of an annulus, a partial annulus, or a variation thereof. The radiation systems may emit a radiation flux such that a substantially uniform dose is delivered to a target area.
