Rectal Retractor for damage-prevention during radiation therapy
Project ID: D2016-57 + D2018-64 Background Effective radiation treatment delivers the maximum possible dose to a tumor while minimizing radiation exposure to the surrounding healthy tissue. Curative doses of radiation can induce chronic morbidities in nearby critical structures. For most cancers in the pelvic region, the dose-limiting organ is the...

Solid Phantom Device for Beam Scanning
Project ID:D2021-29 Radiation therapy is a common curative procedure to treat cancer. The goal of radiation therapy is to expose the tumor to a sufficient dose of radiation so as to eradicate all cancer cells. The radiation dose is often close to the tolerance level of the normal body tissues. It is, therefore, necessary to determine the dosage levels...

Intracavitary Radiation Applicator
Project ID D2005-05 BackgroundHigh Dose Rate (HDR) brachytherapy is an internal radiation treatment that distinguishes itself from external beam radiotherapy by passing a source of radiation through thin tubes placed either within cancerous tissue (interstitial HDR), or inside a body cavity in close vicinity of tumors. These approaches allow treatment...

Concurrent Delivery of Interstitial Thermobrachytherapy in Cancer Treatment
Project ID: D2017-09 Background: Low dose rate (LDR) brachytherapy in prostate cancer treatment is a modality requiring surgical insertion of radioactive seeds in the prostate. The technology offers precise delivery of radiation to the tumoricidal mass while significantly reduces dose to surrounding normal tissue. Hyperthermia, when used with LDR,...
