A 3D wireless tracking system for minimally invasive spine surgery navigation is developed based on the mm-wave radar technique. It has the benefit of multi-target tracking and small-sized transponder. With the cooperation of radar system and triangulation algorithm, the maximum error of 3D positioning is less than 1.8 mm in the distance of 1.2 m..

本技術特點在於使用微波雷達技術實現三維定位追蹤系統。適用於醫療、精密製造等室內、短距離、高準確度需求的應用。

The minimally invasive surgery has small incision and quick recovery, but highly depends on surgeon’s skill. So the requirement of surgery navigation comes up. Our proposed microwave technique overcome the disadvantage of optical technique, which is widely used by the medical equipment companies around the world.
