Extended Reality (XR), which includes Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR), has a revolutionary impact on biomedical applications. It improves visualization, makes surgery more precise, and boosts medical education. This paper looks at how XR fits into healthcare through real-world examples. The paper also groups XR platforms into three levels: cheap, mid-range, and high-end professional gear talking about their costs and how to put them to use. Even though XR shows great promise, it faces some roadblocks. These include computer power limits, location tracking errors, safety risks, and gear-related issues. To keep XR growing and being used more in medicine, we need to tackle these problems with better tech and ethical rules.
