In this paper, we describe a fiber-optic-coupled radiation sensor that can be placed directly at the site of a tumor in a patient that is undergoing radiation therapy. The sensor provides real-time feedback during the therapy procedure allowing for precise control of the delivered dose. It is expected that better control of the radiotherapy parameters will lead to increased survivability statistics and a better overall quality of life for cancer patients.
