Physicians, trainees and even laypeople can now experience what it’s like inside the operating room as an expert radiologist performs one of the most difficult medical procedures of its kind.
Ziv Haskal, MD, of the University of Virginia Health System, has created a dramatic teaching tool using the power of virtual reality. Whether watched on a high-end VR system or a $15 cardboard viewer, Haskal’s virtual procedure puts the viewer right in the operating room with him as he creates a new blood vessel through a small nick in a patient’s neck.
It’s a complicated procedure—Haskal calls it an “interventional radiology heptathlon”—and his use of VR is set to transform how it is taught. “The current means of teaching is a physical person has to arrive … and go over with the doc beforehand. Or they have to look at a lousy 2D animation on a screen,” Haskal said. “Once you put [VR] glasses on people, it’s like you walk them through a completely different door.”
From inside the VR goggles, viewers can look around in 360 degrees as the procedure, known as a transjugular intrahepatic portosystemic shunt, unfolds around them. Haskal guides them step-by-step through the entire procedure, and strategic use of picture-in-picture lets the viewer see both what Haskal is doing and what he is seeing.
Haskal designed the VR experience as a teaching tool for physicians and trainees, but he can foresee many other game-changing applications. VR might be used to show a patient what to expect during a procedure, to teach a nursing student what must be kept sterile in an operating room, or to provide a refresher for physicians who have not performed the procedure recently.
