中文摘要：

在影像引导下的介入操作中,导航技术的应用可减少操作医师对经验的依赖,提高介入穿刺操作的精准性。目前临床影像引导下介入操作中常用的导航技术包括多模态影像融合导航技术和机器人辅助穿刺技术。多模态影像融合导航又分为磁定位导航和光学定位导航。机器人辅助穿刺技术是实现精准定位并辅助人工穿刺的一项技术,缩小了年轻医生与有经验医生之间的差距。

英文摘要：

The navigation techniques can be used to reduce operating physician＇s reliance on experience and improve puncture accuracy in image-guided interventional procedures. Navigation technology includes multimodality image fusion navigation and robotassisted puncture technology. Multimodality image fusion navigation is a real-time navigation technology that combines ultrasound with CT or MRI images to assist the interventional operation. Robot-assisted puncture is a technology of using robot to realize precise positioning and to assist manual puncture. With high stability,strong repeatability,no fear of ionizing radiation and other advantages,navigation technique makes interventional operations more precise and narrows the gap between young and experienced doctors.
