增强现实（AR）在图像引导干预领域的应用越来越广泛，而消费级头戴式显示器（HMD）技术的应用则进一步扩大了这种应用。Microsoft® HoloLensTM光学穿透设备处于消费者技术的最前沿，因为它是第一款无系绳头戴式计算机（HMC）。它在指导临床干预方面显示出有效性，但其准确性和稳定性仍需在临床环境中进行评估。我们已经开发了一个评估协议的HoloLensTM使用光学测量设备来测量所感知的渲染全息图的姿态。这将评估HoloLensTM将全息图保持在预期姿态的能力。当执行可能由于其同时定位和映射中的误差而导致全息图的姿态偏移的动作时，测量稳定性。重点放在更有可能在临床环境中执行的操作上。这将用于确定未来该技术最适用的用例以及如何在使用时最大限度地减少错误。我们的研究结果表明，该设备的潜力，术中临床使用的承诺。必须进行进一步的分析，以评估全息图中断的其他潜在来源。
Augmented reality (AR) has an increasing presence in the world of image-guided interventions which is amplified by the availability of consumer-grade head-mounted display (HMD) technology. The Microsoft® HoloLensTM optical passthrough device is at the forefront of consumer technology, as it is the first un-tethered head mounted computer (HMC). It shows promise of effectiveness in guiding clinical interventions, however its accuracy and stability must still be evaluated for the clinical environment. We have developed an evaluative protocol for the HoloLensTM using an optical measurement device to digitize the perceived pose of the rendered hologram. This evaluates the ability of the HoloLensTM to maintain the hologram in its intended pose. The stability is measured when actions are performed that may cause a shift in the holograms’ pose due to errors in its simultaneous localization and mapping. An emphasis is placed on actions that are more likely to be performed in a clinical setting. This will be used to determine the most applicable use cases for this technology in the future and how to minimize errors when in use. Our results show promise of this device’s potential for intraoperative clinical use. Further analysis must be performed to evaluate other potential sources of hologram disruption.
