About Virtual Phantoms, Inc.
VPI develops a suite of advanced software tools to calculate and report radiation dose to patients who undergo medical examinations involving X-ray, CT, PET, and SPECT imaging modalities, or to workers who are exposed to various occupational radiation sources. With a $1.2 million STTR grant from the NIH/NIBIB, the company was founded in 2009 by faculty members from Rensselaer Polytechnic Institute using the “virtual patient” technologies developed from nearly 20 years research at RPI in the field of nuclear and radiological engineering. Combining a large collection of anatomically accurate models of patients of various ages and sizes and sophisticated “Monte Carlo” simulation methods originally developed for nuclear weapons research at Los Alamos, VPI is recognized as a leader in the modeling of ionizing radiation, radiation safety, and medical/occupational radiation dosimetry.
About Dr. Xu:
Dr. X. George Xu (http://www.rpi.edu/~xug2) ) is currently the Professor and Head of Nuclear Engineering Program at Rensselaer Polytechnic Institute (RPI), Troy, New York. After receiving a Ph. D. in Nuclear Engineering from Texas A&M University, he joined RPI as Assistant Professor (with a joint appointment as the Director of Office Radiation and Nuclear Safety) and was promoted to Associate Professor with tenure in 2001 and then Professor in 2006. In 2011, he was appointed the Head of Nuclear Engineering Program at RPI. In this administrative role, Dr. Xu is responsible for various aspects of the program involving 20 faculty members and 160 undergraduate and graduate students who are supported by two major, internationally known nuclear research laboratories: the Gaerttner 100-MeV electron accelerator facility (LINAC) and the Walthousen Reactor Critical Facility (RCF). Dr. Xu is a fellow of the American Nuclear Society (ANS) and the American Association of Medical Physicists (AAPM).
In research, Dr. Xu belongs to the Rensselaer Radiation Measurement and Dosimetry Group (http://RRDMG.rpi.edu). He and his colleagues are interested in novel computational and experimental methods that have important and diverse applications in radiation protection, radiation measurement, shielding design, reactor modeling, medical imaging, and radiotherapy. In particular, he uses Monte Carlo simulations as a research tool and has more than 20 years of experience in various production Monte Carlo codes. His recent research projects have included such diverse topics as parallel Monte Carlo computing using GPU/CUDA, coupled nuclear reactor neutronics and thermal-hydraulics analysis, nano-materials based x-ray sources, CT imaging and proton radiotherapy, and compressive sensing for nuclear detection.
From 1995 to 2000, Dr. Xu served as the Director of Office of Radiation and Nuclear Safety / Institute Radiation Safety Officer, responsible for the management of a comprehensive radiation and nuclear safety program at RPI. Since 1995, Dr. Xu has directed numerous projects, with a total funding of about $15M from agencies such as National Science Foundation, Department of Energy, National Institutes of Health, National Institute of Standards and Technology, and Electric Power Research Institute, as well as private nuclear power industry including Entergy Nuclear.
By 2012, Dr. Xu had graduated 15 Ph.D. and 10 M.S. students. Mostly with his students, Dr. Xu has authored more than 140 peer-reviewed full papers and chapters, 250 conference abstracts, 90 invited seminars and presentations, 5 patents/disclosures and 5 software packages. An internationally recognized leading expert in Monte Carlo computation and radiation protection dosimetry, Dr. Xu has co-founded the International Consortium of Computational Human Phantoms and co-edited the “Handbook of Anatomical Models for Radiation Dosimetry.”
