Mary Bird Perkins Cancer Center has officially launched its new H.N. Saurage IV Distinguished Lecture series dedicated to innovation in medical physics. On Oct. 20, the Cancer Center welcomed Steve Jiang, PhD, vice chair and chief of the Division of Medical Physics & Engineering at the University of Texas Southwestern Medical Center, to serve as the series’ first guest lecturer. Jonas Fontenot, PhD, chief operating officer, Dr. Charles M. Smith chief of physics, Mary Bird Perkins Cancer Center and dozens of other Cancer Center team members and students were on hand to hear Jiang present “Thoughts on the Deployment of Artificial Intelligence in Clinical Practice.”
The lecture focused on several issues facing successful implementation of AI within the realm of medical physics, such as model generalizability, model deterioration, and model interpretability. Through the course of the lecture, Jiang identified these key barriers that, in his experience, have limited the ability to leverage the power of AI for use in improving patient cancer care.
“AI should know what it does and doesn’t know,” said Jiang, as he proposed a possible use of confidence metrics when reporting AI predictions. Key components of his overall approach to successful clinical deployment included concepts of transparency, common sense, and utility.
“Essentially, there is no magic bullet in AI,” said Jiang. “What works for some will not necessarily work for all, and that is okay. The important thing is that we develop AI tools that truly satisfy a particular clinical need and then strive to characterize and report the uncertainties, tolerance boundaries, and criteria for safe use of that tool. The oncologists at Mary Bird Perkins an excellent precision medicine and AI programs that are getting stronger with time.”
Jiang is one of the nation’s foremost experts on medical physics. He has been instrumental in the development of dozens of publications related to artificial intelligence in medicine and the use of adaptive radiotherapy. In 2013, he joined the University of Texas Southwestern Medical Center, as a tenured full professor, a Barbara Crittenden Professor in Cancer Research, the vice chair of the Radiation Oncology Department, and the director of the Medical Physics and Engineering Division. His research interest includes the development and deployment of artificial intelligence and image processing technologies to solve medical problems. Over the course of Jiang’s career, he has earned numerous awards, including having most recently been elected fellow in the 2022 class of the American Institute for Medical & Biological Engineering (AIMBE) College of Fellows.
This lecture is the first of many planned for the newly formed H.N. Saurage IV Distinguished Lecture Series in Medical Physics.
Supported by the H.N. Saurage IV Family Fund, this lecture series is committed to scientific education for medical physicists, physicians, and other allied health professionals by inviting distinguished researchers from around the world to travel to Louisiana to discuss their discoveries and share their knowledge. It is also designed to highlight opportunities for future work benefitting patients diagnosed with cancer. The H.N. Saurage IV Family Fund provides resources to support travel and accommodations, hosting of the visit and an honorarium for one invited lecturer each year.
The event also highlighted the work that Mary Bird Perkins is doing to cultivate the next generation of cancer researchers. As part of the lecture events, a special lunch poster session was held, showcasing the current high-level research performed by graduate student researchers within the LSU Department of Physics and Astronomy and the joint Mary Bird Perkins – LSU Medical Physics partnership. This event provided a unique engagement opportunity for young researchers to share their work with Jiang, research faculty and staff from Mary Bird Perkins, LSU and other members of the cancer care community.
