碩士 === 國立成功大學 === 機械工程學系碩博士班 === 95 === In this research, we developed an intelligent navigation workflow and computer-aided training system for pedicle screw implantation in spinal surgery. Base on the biplane X-ray imaging of a lumbar saw bone, spatial coordinate correlations between the physical saw bone and the 3D digitizer built an off-line training environment. A senior spine surgeon sketched 2D safety areas on biplane images to be projective intersection to generate 3D safety zones for pedicle insertion. The physicians are able to operate a 3D digitizer to set pedicle drilling position and orientation on saw bones in which 3D visualization is associated to the safety zones. Grading levels were preset by the senior spine surgeon to represent the test results of pedicle screw implantation. The techniques developed in this system involve X-ray imaging rectification, registration, image processing, imaging dilation and erosion, bi-plane calibration, and spatial geometric transformation, which will be a pioneer study of further clinical applications. The same principles of pedicle insertion can be applied to either thoracic or lumbar spine.
