心脏电生理学程序为医生提供了丰富的3D信息，通常在固定的2D监视器上呈现。可穿戴混合现实显示器的新发展提供了简化和增强3D可视化的潜力，同时提供了对手术室内设备的免提动态控制。目的：这项工作的目的是评估的性能和质量的混合现实系统设计用于心脏电生理术中使用。方法：使用适用于电生理学特定用例的现有显示确认程序评价了增强型电生理学可视化和交互系统（ELVIS）混合现实系统性能标准，包括图像质量、硬件性能和可用性。通过10例患者的人体观察性研究（工程ELVIS（E2）研究）进行了额外的性能和用户确认。结果如下：ELVIS系统实现了可接受的帧速率、延迟和电池运行时间，具有可接受的动态范围和深度失真以及最小的几何失真。台架试验结果与观察性研究中的医生反馈一致，并注意到几何理解的潜在改善。结论：ELVIS系统基于当前市售的混合现实硬件，能够满足电解剖标测显示器的硬件性能、图像质量和可用性要求，以便在电生理手术中实时使用。将现成的混合现实硬件用于特定的临床用途可以加速这种变革性技术的采用，并提供对临床相关数据的实时可视化，理解和控制。
Cardiac electrophysiology procedures present the physician with a wealth of 3D information, typically presented on fixed 2D monitors. New developments in wearable mixed reality displays offer the potential to simplify and enhance 3D visualization while providing hands-free, dynamic control of devices within the procedure room. Objective: This work aims to evaluate the performance and quality of a mixed reality system designed for intraprocedural use in cardiac electrophysiology. Method: The Enhanced Electrophysiology Visualization and Interaction System (ELVIS) mixed reality system performance criteria, including image quality, hardware performance, and usability were evaluated using existing display validation procedures adapted to the electrophysiology specific use case. Additional performance and user validation were performed through a 10 patient, in-human observational study, the Engineering ELVIS (E2) Study. Results: The ELVIS system achieved acceptable frame rate, latency, and battery runtime with acceptable dynamic range and depth distortion as well as minimal geometric distortion. Bench testing results corresponded with physician feedback in the observational study, and potential improvements in geometric understanding were noted. Conclusion: The ELVIS system, based on current commercially available mixed reality hardware, is capable of meeting the hardware performance, image quality, and usability requirements of the electroanatomic mapping display for intraprocedural, real-time use in electrophysiology procedures. Verifying off the shelf mixed reality hardware for specific clinical use can accelerate the adoption of this transformative technology and provide novel visualization, understanding, and control of clinically relevant data in real-time.
