Cone-beam computed tomography (CBCT) for adaptive image guided head and neck radiation therapy

Adaptive (ART) and image guided radiation therapy (IGRT) can improve target coverage and reduce unnecessary irradiation of organs at risk (OAR). The purpose of this study is to report the results of using mid-course imaging and a novel workflow with cone-beam computed tomography (CBCT) surveillance of dose to OAR to trigger adaptive replanning in head and neck radiotherapy.Impact of radiation therapist (RTT) managed match protocol and mid-course...
