BRACHYTHERAPY APPLICATOR AND METHODS FOR GENERATING ANISOTROPIC DIRECTIONAL RADIATION PROFILES

摘要

A brachytherapy applicator including an elongated intracavitary applicator, a plurality of channels disposed within the elongated intracavitary applicator, at least one shielding element, and configured to receive at least one radioactive element. In some instances, the at least one shielding element and the at least one radioactive element may be selectively positioned within the channels of the elongated intracavitary applicator to generate a desired anisotropic directional radiation profile for the treatment of cancer.
