Brachytherapy Dosimetry

In brachytherapy procedure, radioactive devices, including solid "seeds" or activity filled balloons, are inserted into the body, adjacent to the cancerous tissue, or in the case of intravascular brachytherapy, within the artery. In this way, high doses of radiation can be delivered to the target, with minimal exposure to other tissues of the body.

CDE can set up radiation transport physics models to accurately determine dose depth profiles around such devices, regardless of the number of devices or geometry, and taking into account the material composition of the tissue, and possible multiple dose contributions from multiple devices.
