交互式图像导向(Interactive Image-Guided-IIG)外科手术需要在手术前的扫描上同步显示出手术设备的尖端。该显示可以让外科医生对当前手术的位置相对于手术重要位置点进行定位。我们开发了一种用于IIG外科手术设备中的基于六自由维关节式手臂的技术。该手臂的设计精度 Interactive Image-Guided-IIG Surgery requires the simultaneous display of the tip of the surgical device on a pre-operative scan. This display allows the surgeon to position the current surgery relative to the point of major surgery. We have developed a technique based on the six-freedom articulated arm used in IIG surgical devices. The arm’s design accuracy
