Pencil beam scanning proton therapy (PBSPT) utilizes spot scanning and proton beam, therefore, it can conform to treatment target at different depths better than typical IMRT, which uses scattered photon beams. Such advantages place more rigorous requirement of PBSPT over volume image guidance than IMRT because it is more susceptible to uncertainties over CT simulation and CBCT image guidance. Numerous opportunities would be pointed out for theoretical and experimental young medical physicists to improve proton beam transport dose accuracy in the heterogeneous patient beam paths.


Biography Liyong Lin, Ph.D., DABR, is Assistant Professor in the Department of Radiation Oncology at Emory University School of Medicine. An ABR board-certified medical physicist, Dr. Lin's expertise includes commissioning, quality assurance and Monte Carlo characterization of pencil beam scanning proton therapy systems. Education Dr. Lin received his Ph.D. in Medical Physics from the University of Wisconsin-Madison. He then completed a two-year clinical postdoc at University of Florida Proton Therapy Institute. Research Dr. Lin's current research interest is in developing Monte Carlo dose calculation and Image-Guided Proton Therapy physics framework for heterogeneous and moving tumors. He serves on the editorial board of Journal of Applied Clinical Medical Physics, as well as on American Association of Physicists in Medicine's Task Group 290 Respiratory Motion Management for Particle Therapy and on Particle Therapy Co-Operative Group's Imaging Sub-committee.
