Superselective intra-arterial infusion for oral cancer has a high anti-cancer effect. Images made by preoperative computed tomography angiography(CTA) and intraoperative digital subtraction angiography(DSA) guide placement of a catheter, which remains in the target artery. However, only these images sometimes cannot help surgeons perform the difficult catheterization. In this report, we present a novel navigation system. This system detected patient's position and orientation by gradient information of maxilla-dental-arch and performed registration by three dimensional CTA image. We made a phantom based on CTA data and we evaluated target registration error(TRE). Measurement device was the optical tracker(NDI Polaris). To evaluate accuracy by the model, the dodecahedron with 1mm hole on each surface was made on the artery bifurcation. At the lingual-facial artery, TRE was satisfied the requirement in one case, this system suggested possibility of adaptation to the superselective intra-arterial infusion.
