摘　　要：目的为计算机辅助立体定向设备的研发设计的，可以依据CT扫描数据进行三维重建并模拟临床腩出血操作过程的颅骨模型。方法以融解的石蜡灌铸内置有假想病灶的颅骨标本制为颅骨模型，采集CT扫描后的序列DICOM数据，通过自编软件平台进行3D重建、手术规划，由计算机辅助立体定向设备对该模型进行模拟微创穿刺。结果完成蜡灌铸的脑出血颅骨模型，且该模型在CT扫描和之后的3D重建中可清晰显示和区别标记物、骨骼、石蜡、假想病灶。结论蜡铸脑出血颅骨模型方法简单、可反复建模，能较理想地评估计算机辅助立体定向设备原型机的系统性能。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. Method Melted paraffin was poured in a skull exemplar in which supposititious 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. Results Pour-in-waxed hemorrhage model of human skull was successful. The marker, skull, paraffin and supposititious focus could be displayed apparently and distinctively in CT images and following 3D reconstruction. Conclusions The model is simple, cheap, reproducible, and also ideal to evaluate system performance of prototype of computer-aided stereotaxic device.
