Dosimetry of Modulated Arc Prostate Radiation Therapy using Gafchromic EBT3 Film Deployed on a Spacer Device

Radiotherapy is one of the most widely used treatment modalities in modern oncology; it is constantly improving, with many high precision tools such as rectal spacers to decrease rectal wall toxicity being used to improve patient outcomes. This thesis explores the idea that in-vivo rectal wall measurements can be performed using Gafchromic EBT3 film deployed on a rectal spacer device known as Rectafix®.
