Graphics Processing Unit-Based High Performance Computing in Radiation Therapy

This book first gives an overview of the applications of Graphics Processing Unit (GPU) for radiation therapy issues. Basic concepts in GPU programming are discussed, together with its advantages and limitations. The second and third parts of the book present GPU applications in a variety of imaging-related issues and therapy-related problems in radiotherapy. The last part discusses potential advanced clinical applications supported by GPU technology. Readers benefit from an in-depth review of GPU-based high-performance computing in radiation therapy.

Xun Jia, Ph.D., DABR, received his PhD in physics from the University of California Los Angeles in 2009. After his postdoctoral training at University of California San Diego, he joined the faculty team at the Department of Radiation Medicine and Applied Sciences, UCSD in 2011. At UCSD, he developed a number of GPU-based applications to accelerate computationally challenging problems in radiation therapy, including compressed sensing-based low-dose cone beam CT reconstruction and Monte Carlo-based radiation dose calculations. He has coauthored 50 papers published in top peer-reviewed journals in the medical physics field. He is also an active manuscript reviewer for many journals and conferences and is currently serving as a Section Editor for theJournal of Applied Clinical Medical Physics.

Steve B. Jiang, Ph.D., DABR, received his PhD in medical physics from the Medical College of Ohio, and his postdoctoral training at Stanford University. He is currently a professor and the Chief of Division of Medical Physics and Engineering at the Department of Radiation Oncology, University of Texas Southwestern (UTSW) Medical Center. Prior to joining UTSW, he was a tenured professor and the Director of Division of Technology Research at the Department of Radiation Medicine and Applied Sciences, UCSD, and served as Executive Director of the Center for Advanced Radiotherapy Technologies, UCSD. Dr. Jiang pioneered the development of high-performance GPU applications for adaptive radiation therapy. He has published over 110 manuscripts in medical physics journals and over 10 book chapters/review articles. Dr. Jiang served as an Associate Editor forMedical Physics, and as a member of the Editorial Board of Physics in Medicine and Biology. He is also a fellow of American Association of Physicists in Medicine.
