Research Focus
Dr. Shawn Xiang's research lab at the University of California, Irvine focuses on advancing proton therapy for cancer treatment through innovative imaging technologies. The lab is developing new methods to accurately map the Bragg peak—where proton therapy is most effective—using protoacoustic and ultrasound imaging. This research aims to improve treatment precision, enhance patient safety, and facilitate clinical adoption of new dosimetry techniques. By integrating these imaging systems, the lab seeks to push the boundaries of radiation oncology and reduce side effects of treatment for patients.
