Our research goal is to enhance and improve proton radiotherapy. Precise delivery of the radiation dose to the patient is the key in spot scanning proton radiotherapy. Therefore, it is important to track every single spot and understand the uncertainty in spot position and patient dose. Our technique involves analyzing the spot position and dose from treatment records from the treatment delivery system, and confirming the information with measurement. The goal of this project is to understand the spot position and dose uncertainties. Treating a moving target with spot scanning proton is challenging because the interaction between the moving target (i.e., lung tumors) and the proton beam is not well understood. We are tackling this problem with measurements in custom-built lung phantoms.
Projects/Techniques: A student working on a research tutorial would have the opportunity to learn how to perform measurements and data analysis at the proton center. The student would also learn to use the proton treatment planning system.
