have developed a prototype that allows them to see the trajectory of their devices in 3D. “It could represent a whole new way to perform our jobs,” he says.
That may still be a long way off, says Bradford Wood, MD, IR chief at the National Institutes of Health (NIH) Clinical Center. “There are many techniques searching for a home—a true clinical need—and there are a lot of hurdles on the way. It’s one thing to do planning and simulation, but the real value is yet to come. The ability to superimpose images during interventions and get feedback that allows iterative modification is the goal.” These applications are especially challenging because organs and targets move during procedures, says his colleague, Sheng Xu, PhD, of the NIH Clinical Center Radiology and Imaging Sciences Department.
Information becomes old in a nanosecond, Dr. Wood notes, and must be updated in real time. There’s additional challenge in keeping track of the physician’s eyes and head. “Gaming

Student and patient education. Dr. Gupta describes medical education as the low-hanging fruit of these technologies. “IR can be daunting for beginners,” he says. “Further, there is no good way to set up a cost-effective simulation environment. Using VR to demonstrate these procedures could bring the barriers way down.”
Further, AR scenarios can facilitate training for rare occurrences otherwise only encountered over a lifetime of learning, notes Barbara Brawn-Cinani, associate director of the Maryland Blended Reality Center.
Using these technologies to engage learners is a passion for Ziv J Haskal, MD, FSIR, editor-in-chief of the Journal of Vascular and Interventional Radiology (JVIR) and professor of radiology at
