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...
