超声穿刺道在透视图像上的虚拟投影辅助经皮肾穿刺
Aid to Percutaneous Renal Access by Virtual Projection of the Ultrasound Puncture Tract onto Fluoroscopic Images
摘要：
背景和目的：在经皮肾镜取石术（PCNL）的背景下，经皮肾穿刺是一项困难的技术，需要快速和精确地进入特定的杯。我们提出了一个计算机化的系统，旨在改善经皮肾穿刺超声穿刺道投影到透视图像。材料和方法：该系统由一台计算机和一个定位器，允许空间定位的各种仪器的位置。在没有任何人为干预的情况下，超声肾造口术道实时叠加到以各种视图采集的荧光透视图像上。结果：我们测试了我们的方法通过实验室实验上的幻影。此外，在我们机构的伦理委员会批准后，我们在手术室中对一例患者的PCNL进行了验证。结论：我们的系统是可靠的，没有图像处理程序，使其强大。我们已经启动了一项前瞻性研究，以验证这项技术既为PCNL专家，并作为一种学习工具。
英文摘要：
Background and Purpose: Percutaneous renal access in the context of percutaneous nephrolithotomy (PCNL) is a difficult technique, requiring rapid and precise access to a particular calix. We present a computerized system designed to improve percutaneous renal access by projecting the ultrasound puncture tract onto fluoroscopic images. Materials and Methods: The system consists of a computer and a localizer allowing spatial localization of the position of the various instruments. Without any human intervention, the ultrasound nephrostomy tract is superimposed in real time onto fluoroscopic images acquired in various views. Results: We tested our approach by laboratory experiments on a phantom. Also, after approval by our institution's Ethics Committee, we validated this technique in the operating room during PCNL in one patient. Conclusion: Our system is reliable, and the absence of image-processing procedures makes it robust. We have initiated a prospective study to validate this technique both for PCNL specialists and as a learning tool.
