介绍。在一项由两部分组成的研究中评估 CT 引导介入手术的定量 3D 导航系统的准确性。材料和方法。在腹部和胸部模型中进行了 22 次手术。评估 3D 解剖图配准和导航的准确性。记录导航过程所用的时间。在 IRB 批准的临床评估中，招募了 21 名计划进行 CT 引导下胸部和肝脏活检和消融的患者。 CT 引导手术是在不遵循 3D 导航显示的情况下进行的。评估了导航的准确性以及系统的工作流程适应性。结果。在模型中，平均 3D 解剖图配准误差为 1.79 毫米。肝脏中单次和两次手术的平均导航针放置精度分别为 2.0 +/- 0.7 毫米和 2.8 +/- 1.1 毫米，肺部为 2.7 +/- 1.7 毫米和 3.0 +/- 1.4 毫米。对于所有程序，人体 3D 导航系统的平均准确度为 4.6 毫米 +/- 3.1。该系统适合 CT 引导干预的现有工作流程，影响最小。结论。 3D 导航系统可以沿着现有的工作流程执行，并且有可能在 CT 引导的介入手术中导航精确的针放置。
Introduction. To evaluate the accuracy of a quantitative 3D navigation system for CT-guided interventional procedures in a two-part study. Materials and Methods. Twenty-two procedures were performed in abdominal and thoracic phantoms. Accuracies of the 3D anatomy map registration and navigation were evaluated. Time used for the navigated procedures was recorded. In the IRB approved clinical evaluation, 21 patients scheduled for CT-guided thoracic and hepatic biopsy and ablations were recruited. CT-guided procedures were performed without following the 3D navigation display. Accuracy of navigation as well as workflow fitness of the system was evaluated. Results. In phantoms, the average 3D anatomy map registration error was 1.79 mm. The average navigated needle placement accuracy for one-pass and two-pass procedures, respectively, was 2.0 +/- 0.7 mm and 2.8 +/- 1.1 mm in the liver and 2.7 +/- 1.7 mm and 3.0 +/- 1.4 mm in the lung. The average accuracy of the 3D navigation system in human subjects was 4.6 mm +/- 3.1 for all procedures. The system fits the existing workflow of CT-guided interventions with minimum impact. Conclusion. A 3D navigation system can be performed along the existing workflow and has the potential to navigate precision needle placement in CT-guided interventional procedures.
