Percutaneous tumor ablation has become a widely accepted and used treatment option for both soft and hard tissue malignancies. The current standard-of-care techniques for performing these minimally invasive procedures require providers to navigate a needle to their intended target using two-dimensional (2D) US or CT to obtain complete local response. These traditional image-guidance systems require operators to mentally transpose what is visualized on a 2D screen into the inherent three-dimensional (3D) context of human anatomy. Advanced navigation systems designed specifically for percutaneous needle-based procedures often fuse multiple imaging modalities to provide greater awareness and planned needle trajectories for the avoidance of critical structures. However, even many of these advanced systems still require mental transposition of anatomy from a 2D screen to human anatomy. Augmented reality (AR)-based systems have the potential to provide a 3D view of the patient's anatomy, eliminating the need for mental transposition by the operator. The purpose of this article is to review commercially available advanced percutaneous surgical navigation platforms and discuss the current state of AR-based navigation systems, including their potential benefits, challenges for adoption, and future developments.

经皮肿瘤消融已成为软组织和硬组织恶性肿瘤广泛接受和使用的治疗选择。目前用于执行这些微创手术的标准护理技术要求医护人员使用二维（2D）超声或CT将针引导至预定目标，以获得完全的局部反应。这些传统的图像引导系统要求操作人员在脑海中将二维屏幕上看到的内容转换为人体解剖结构固有的三维（3D）环境。专门为基于经皮针的手术设计的先进导航系统通常融合多种成像模式，以提高对关键结构的认识并规划针的轨迹，避免损伤关键结构。然而，即使是许多这些先进系统，仍然需要操作人员在脑海中将二维屏幕上的解剖结构转换为人体解剖结构。基于增强现实（AR）的系统有可能提供患者解剖结构的三维视图，消除操作人员进行脑海转换的需要。本文的目的是回顾市售的先进经皮手术导航平台，并讨论基于AR的导航系统的现状，包括其潜在优势、采用面临的挑战以及未来发展。计算机应用-虚拟成像、技术评估、增强现实、手术导航、经皮消融、介入放射学©RSNA，2025年。
