Abstract
A polymeric radiation-source with customized geometries to maximize receipt of radiation into treatment areas that is formed from either radioisotopes molecularly bonded to a polymer or radioisotopes encased within a polymer.
Claims20
A system for creating and using a customized polymeric radiation-source comprising:
- a device for obtaining image data of a treatment area comprising human tissue with contours and a regular geometry, the image data including shape, volume, and surface geometry data;
- a customized polymeric radiation-source formed from a regular radioactive polymer having a complex of a radioisotope and a bi-functional ligand molecularly bonded with a polymer, the customized polymeric radiation-source matching the contours and regular geometry of the treatment area in accordance with the image data, the customized polymeric radiation-source having a first thickness;
- and
- a radiation shielding layer formed adjacent to the customized polymeric radiation-source, the radiation shielding layer having a geometry that mirrors the contours and regular geometry of the customized polymeric radiation-source, the radiation shielding layer having a second thickness at least equal to the first thickness of the customized polymeric radiation-source, the radiation shielding layer containing or limiting radiation emitted from the customized polymeric radiation-source.
