Due to breathing motion, lung tumours move during stereotactic body radiation therapy (SBRT). Scatter imaging, which collects photons scattered out of the radiation therapy beam, is a potential technique for real-time tracking of lung tumours. His research focuses on developing novel imaging techniques to guide radiation therapy.
