本系統可分為三大部分,影像重建,座標規劃,及方位校準。在影像重建方面是將二維醫學影像重建出立體模型,並提供多種切割功能以利醫師分離破碎骨骼或病灶。座標規劃方面是調整目前骨骼的彼此相對座標關係求得最佳手術位置,並記錄下各部位骨骼相對移動量以便術中比較。方位校準技術中採用附加標記定位法,利用術前貼在病患身上的附加標記實際座標與影像中的附加標記影像座標彼此找出轉換關係。找到轉換關係後,便可將目前鎖在骨骼上的手術器械位置與術前規劃好的目標偏移量比較,協助醫師將完成手術。
本研究採用光學式定位裝置,並採用相對位移量來導引手術位置,因而可以將方位校準時的誤差減少,適合於顱顏整型手術或骨科手術等需要相對位移精準的手術,經過實驗誤差均低於1mm 應符合實際手術需求。
