【Abstract】 Purpose To test domestic Excelim-04TM Neuronavigation system′s precision and feasibility. Methods By using Peg-Board Phantom,we calculated the localization precision of the definite points,that is the distance between the point in CT or MRI images and the actual location that the navigation system shows.Then we analyzed the facts that influence the precision of the navigation system. Results Excelim-04TM navigation system showed high precision by using CT data.In emulative intra-operational navigation,the Excelim-04TM neuronavigation system showed high precision and stability.This navigation system can satisfy clinical requirements. Conclusions Excelim-04TM neuronavigation system shows high precision and stability,and can be used in the neurosurgical navigational operations.更多还原
