精准空间透视融合手术导航

High-precision Three-dimensional Space See-through Surgical Navigation

面对大众对创伤性小、恢复期短、更安全高效的微创手术需求,手术导航的临床重要性日渐显著。如何使用医学影像信息指导术前手术规划,在术中引导实时诊断、精确操作与高效治疗,提高手术效率、精度与安全成为研究关注热点。本文针对临床需求提出一种基于高性能立体全像技术的新型精准空间透视融合手术导航系统,并且介绍了该导航系统涉及到的关键技术。基于该系统能够实现对微创手术器械追踪与手术感兴趣区域中关键解剖组织的三维立体增强显示,为医生提供精确直观的透视融合引导。

Image guided surgery has shown increasing importance as the public is in need of a surgical procedure that is minimally invasive, requires short recovery time, and can be performed in a safer and more efficient way. Current researches focus on how to utilize medical images to guide preoperative planning and to intraoperatively ensure real-time diagnosis, high-accurate operation, and high-efficient treatment. This paper proposed a surgical navigation technique and system for specific clinical scenarios, and provided an integral videography three-dimensional（3D） image based high-precision augmented reality. Key technologies involved in the surgical navigation system were also introduced. The surgical tools can be tracked in real time and updated in 3D display. Using 3D image overlay system, 3D autostereoscopic images of critical anatomy structures and tools can be observed with naked eyes in surgical scene. The proposed system can provide intuitive and precise guidance for surgeons by providing a ＂see-through＂ 3D augmented scene.
