A radiation applicator system is structured to be mounted to a radiation source for producing 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 (10) includes an applicator and, in some embodiments, an adapter. The adapter is formed for fixedly securing the applicator to a radiation source (40), such as the x-ray source of 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 applicator head, wherein the head 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 (48) includes the applicator head (30), which defines a concave treatment surface for engaging and, preferably, supporting the area to be treated with a predefined dose of radiation. The applicator can include a low energy radiation filter inside of the applicator head to reduce undesirable low energy radiation emissions. A plurality of applicators having applicator heads of different sizes and shapes can be provided to accommodate treatment sites of various sizes and shapes. And, an adaptable applicator having a plurality of radiation positions can be provided to deliver a substantially cylindrical dose of radiation.
