Chasing the Light: What More We Can Learn from the X-ray and Tissue Interactions

Abstract:

Traditional medical physics research focuses on the energy deposition of MV X-rays for radiotherapy and attenuation for kV X-ray imaging. Nevertheless, the secondary particles of X-ray tissue interaction carry rich information that should be integrated and utilized. The presentation will discuss the technology, clinical applications, and future developments of two unique and new modalities using these secondary particles.

Bio:

Dr. Ke Sheng graduated from the University of Science and Technology of China with B.S. and M.S. before obtaining his Ph.D. in Medical Physics from the University of Wisconsin, Madison, in 2004. He was then an Assistant and Associate Professor at the University of Virginia. In 2011, Dr. Sheng moved to the University of California, Los Angeles, where he was promoted to Full Professor with Tenure and Director of Physics Research. In 2022, he joined UCSF Radiation Oncology as the Vice Chair of Medical Physics. He has broad research interests in radiotherapy and medical imaging, including treatment planning, optimization, image reconstruction, processing, machine learning, robotics and radiobiology. He was elected Fellow of AAPM in 2016. His research has been supported by NIH, DOE, DOD, and industrial partners. He has published over 180 peer-reviewed papers and mentored over 20 Ph.D. students.
