Advanced laparoscopic procedures, particularly laparoscopic liver resection and ablation, may benefit from image-guided surgery techniques that involve interactive three-dimensional imaging and instrument tracking.
A prototype system for laparoscopic ultrasound-guided radiofrequency ablation was designed and implemented. This system uses an infrared camera to track instruments and runs on a personal computer. Features of the system include spatially registered ultrasound visualization, volume reconstruction, and interactive targeting. Targeting of accuracy studies was performed by directing a tracked needle to a phantom target.
Ultrasound data collection and volume reconstruction can be achieved within minutes and interactively reviewed by the surgeon. Early results with phantom experiments demonstrate a targeting accuracy of 5 to 10 mm.
These results support the further development of this and similar image-guided surgery systems for specific laparoscopic procedures. Eventually, rigorous clinical evaluation will be necessary to prove their value.
先进的腹腔镜手术，尤其是腹腔镜肝切除和消融术，可能会受益于涉及交互式三维成像和器械跟踪的图像引导手术技术。
设计并实现了一种用于腹腔镜超声引导下射频消融的原型系统。该系统使用红外摄像头跟踪器械，并在个人计算机上运行。该系统的特点包括空间配准超声可视化、容积重建和交互式靶向。通过将跟踪针指向模拟目标来进行靶向准确性研究。
超声数据采集和容积重建可在数分钟内完成，并可供外科医生进行交互式查看。模拟实验的早期结果显示靶向精度为5至10毫米。
这些结果支持进一步开发此系统及类似的用于特定腹腔镜手术的图像引导手术系统。最终，需要进行严格的临床评估以证明其价值。
