背景和目的光学透明头戴式显示器（ost - hmd）提供混合现实（MixR）体验，在使用高分辨率放射成像的过程中实现无阻碍的手术部位可视化。本技术说明描述了我们使用OST-HMD作为传统血管造影套件监视器替代经皮脊柱手术的初步经验。方法采用Microsoft HoloLens系统实现MixR可视化。各种脊柱手术（椎体成形术、后凸成形术和经皮椎间盘切除术）采用市售设备对腰椎假体进行。HMD通过在介入者的视野上叠加虚拟的后前方和侧面视图，创造了一个实时的MixR环境。从操作员的角度拍摄了整个过程。回顾录像以评估关键的解剖标志和材料是否可靠地可视化。记录剂量测定和手术时间。操作人员在每个操作之后完成了一份调查问卷，详细说明了优点、局限性和可视化模式偏好。结果经皮椎体成形术、后凸成形术和椎间盘切除术均在腰椎幻影的OST-HMD图像引导下成功完成。剂量学和手术时间优于典型手术时间。常规和MixR可视化模式在提供图像引导方面同样有效，可以可靠地显示关键的解剖标志和材料。结论本初步研究证明了利用ost - hmd在脊柱介入性手术中进行图像引导的可行性。这种新颖的可视化方法可以作为微创经皮脊柱治疗中有价值的辅助工具。
Background and purpose Optical see-through head mounted displays (OST-HMDs) offer a mixed reality (MixR) experience with unhindered procedural site visualization during procedures using high resolution radiographic imaging. This technical note describes our preliminary experience with percutaneous spine procedures utilizing OST-HMD as an alternative to traditional angiography suite monitors. Methods MixR visualization was achieved using the Microsoft HoloLens system. Various spine procedures (vertebroplasty, kyphoplasty, and percutaneous discectomy) were performed on a lumbar spine phantom with commercially available devices. The HMD created a real time MixR environment by superimposing virtual posteroanterior and lateral views onto the interventionalist's field of view. The procedures were filmed from the operator's perspective. Videos were reviewed to assess whether key anatomic landmarks and materials were reliably visualized. Dosimetry and procedural times were recorded. The operator completed a questionnaire following each procedure, detailing benefits, limitations, and visualization mode preferences. Results Percutaneous vertebroplasty, kyphoplasty, and discectomy procedures were successfully performed using OST-HMD image guidance on a lumbar spine phantom. Dosimetry and procedural time compared favorably with typical procedural times. Conventional and MixR visualization modes were equally effective in providing image guidance, with key anatomic landmarks and materials reliably visualized. Conclusion This preliminary study demonstrates the feasibility of utilizing OST-HMDs for image guidance in interventional spine procedures. This novel visualization approach may serve as a valuable adjunct tool during minimally invasive percutaneous spine treatment.
