Tong Xu

Associate Professor, Department of Physics
Professor Xu’s primary focus is the application of physics to enhance medical diagnostics and treatment through advanced imaging technologies.
His research involves the use of implanted positron emission markers and position-sensitive detector for real-time motion tracking of targets such as organs, tumors, and surgical instruments to improve medical procedures.
Professor Xu has also developed a Dynamic Dual-Energy X-ray Imaging (dDEXI) technique that simultaneously captures two image sequences, eliminating motion artifacts. This method improves visualization of internal organ motion by separating bone and soft tissue signals, enhancing the accuracy of lung disease diagnostics, including emphysema and chronic obstructive pulmonary disease (COPD).
