he ever-growing processing power of computers in smaller and more accessible packages has created a space
for technologies such as virtual reality (VR), augmented reality (AR) and mixed reality (MR)—collectively known as extended reality (XR).
VR has thus far been implemented by replacing a user’s visual field with a screen—whether that’s through a mobile device as seen in Google’s Cardboard or with a complex headset connected to a powerful PC such as the Oculus. AR and MR are more ambiguous terms that generally refer to the projection
of a virtual image into reality or an alteration of how the user would see or interact with their environment. One example is the “placement” of virtual furniture in a room by many mobile shopping applications before purchasing the product. The culmination of both VR and AR is XR, which encompasses the constantly changing spectrum of technologies that toe the edge between science fiction and reality. With these advances in XR technologies, the possibilities for medical application— especially in an innovative and high-tech field like interventional radiology—have never been broader.
What XR could mean for IR Enhanced engagement within XR-driven virtual environments offers unique potential within IR, a field where strong spatial understanding of often complex patient anatomy is essential. Several field-relevant applications of VR and AR have been developed in recent years showing promise for shifting paradigms within the field.
Training At the SIR 2018 Annual Scientific Meeting, Ziv J Haskal, MD, FSIR, demonstrated possible XR applications in medical training with a 360-degree
