A 3D Printed Patient Specific In-Vivo Dosimetry System

Abstract

While radiotherapy treatments are meticulously planned, checked, and verified before the patient arrives at the clinic, once the treatment commences, there is often no direct monitoring of the radiation dose received by the patient. Improved safety and treatment accuracy for patients undergoing radiotherapy can be accomplished by using in-vivo dosimetry. However, most commercially available detectors are best suited to measuring radiation in a quality control and assurance setting. As a result, their designs are often too fragile, bulky, or complex for direct use on patients, limiting the routine clinical use of in-vivo dosimetry. This thesis aims to address this limitation by using 3D printing to develop a wireless radiation detector capable of addressing the clinical need for in-vivo dosimetry of patients undergoing radiotherapy.
