Medical Physics and Engineering Division
Welcome to the Division of Medical Physics and Engineering, a branch within the Department of Radiation Oncology at UT Southwestern Medical Center.
Our Division is composed of more than 80 employees, including medical physics faculty, medical dosimetrists, engineers, programmers, IT personnel, administrative staff, medical physics residents, postdoctoral fellows, graduate students, and visiting scholars and students.
We are engaged in three primary areas of activity: clinical service and consultation, research and development, and education.
Our vision is to become one of the world’s leading academic medical physics programs in all three areas by working closely with clinicians and researchers in other relevant areas to solve important clinical problems through technological innovation.
Dr. Steve Jiang, Vice Chair and Professor; Dr. Xun Jia, Professor; and Dr. Dan Nguyen, Assistant Professor, in collaboration with Varian Medical Systems Inc., received a $2.9M NIH Academic-Industrial Partnerships R01 grant to develop human-like AI agents for better and faster radiotherapy treatment planning. This is the second R01 grant received by three multiple principal investigators to develop AI tools for improving cancer radiotherapy.
Dr. Xiangkun Xu was awarded the 2021 Spring Conference Travel Award by the UT Southwestern Postdoctoral Association.
Dr. Xun Jia, Professor of Radiation Oncology, in collaboration with Dr. Anke Henning, Professor of Radiology and Director of the Advanced Imaging Research Center, received a $250,000 grant to develop a new MRI scanner that will help keep radiation focus on tumors in radiotherapy. Instead of using MRI imaging conducted days or weeks ago, the MRI Dr. Jia is developing will attach to radiotherapy equipment and show MRI images immediately before or during radiation treatment. This will help see the tumor and target the radiation. The current state-of-the-art radiotherapy uses cone-beam computed tomography attached to radiotherapy equipment to guide radiation delivery. The new MRI scanner will enable better tumor visualizations without the concern of X-ray exposure in computed tomography.
This year's joint AAPM/COMP meeting was held virtually July 12 - 16. This year's theme was Improving Health Quality. Increasing Global Impact. Our Department participated in dozens of posters and presentations.
Xiao Liang, Liyuan Chen, Dan Nguyen, Zhiguo Zhou, Xuejun Gu, Ming Yang, Jing Wang, and Steve Jiang—all part of our Department—were just awarded the Roberts’ Prize for best paper published in the journal of Physics in Medicine and Biology for 2019. Their paper is entitled “Generating synthesized computed tomography (CT) from cone-beam computed tomography (CBCT) using CycleGAN for adaptive radiation therapy.”
