摘要
为了实现人工骨植入体内的有效活化,提出基于CT图像、RE(逆向工程)和CAD技术的人工骨三维活化结构数字化设计方法。首先对患者需要人工替代骨的部位健侧进行CT扫描,获得其二维断层扫描图像,利用图像处理技术及RE(逆向工程)技术实现个性化人工替代骨表面复杂曲面数字化三维模型重建,然后再结合三维CAD建模技术分别设计符合一定孔隙率的骨骼外形结构和内部结构,最后将骨骼外形复杂曲面数据与骨骼外形结构/内部结构合并、组装得到仿生的人工骨活化结构支架设计模型。
In order to realize effective activation of Artificial Bone, digital simulation design of the Artificial Bioactive Bone is put forward. First CT scanning of the healthy part is made about substituted bone of the sufferer; 2D scanning image is obtained; and image manipulation and reverse engineering is used to achieve 3D digital simulation modeling of individualization artificial substitute bone exterior. By combining 3D modeling technology, exterior structure and interior structure of bones is designed to meet the hole ratio. In the end, complexity of bones exterior is united with exterior structure / interior structure of bones to obtain scaffold modeling of Artificial Bioactive Bone.
