面向RPM的颈椎置钉瞄准器的CAD反求技术

CAD reverse technique for RPM about the collimator for setting nails on cervical vertebra

介绍CT图像的反求步骤、数据格式转换、图形矢量化技术在边缘强化过程中的应用。该方法为快速原型制造系统(RPM)获取椎弓根螺钉置钉瞄准器的前端数据提供了可行的技术路线。

The study introduces the application of reverse approach, transition of data format and figure vector technique of CT image in process of edge intensifying. This method provides a feasible technical route to obtain pre-data of the collimator for RPM.
