Creation And 3-dimensional Reconstruction Of Hemorrhage Model Of Human Skull And Its Application On Stereotactic Surgery System

OBJECTIVE: For the invention of computer-aided stereotaxic device, the model of human skull was designed,with that the 3-dimensional (3D) virtual model could be reconstructed by datum from computed tomography (CT) and the process of clinical minimally invasive neurosurgery of intracerebral hemorrhage (ICH) could be simulated.METHODS: Melted paraffin wax was poured in a skull exemplar in which suppositious focus had been installed previously. After scanning of CT, the corresponding serials of DICOM datum was collected, 3D reconstruction and preoperative planning was made on software platform. Finally, puncture to this model was simulated by compute-aided stereotaxic device.RESULT: Pour-in-waxed hemorrhage model of human skull was successful, and marker, skull, paraffin wax and suppositious focus could be displayed apparently and distinctively in CT images and following 3D reconstruction.CONCLUSION: The model is simple, cheap, reproducible, and also ideal to evaluate system performance of prototype of computer-aided stereotaxic device.
