| 摘 要： | 针对医学上广泛采用的CT图像数据，提出了基于CT图像的快速成形数据建模方法，通过CT图像滤波，分割，开操作等图像处理方法以及轮廓提取和采样等建模方法，得到快速成形数据接口CLI文件，进而进行原型的快速成形制造。该方法在人体右侧半骨盆置换手术中取得成功，讨论了提高模型精度，构造数据接口文件的有关问题。

| Abstract: | Aiming at the CT technology is widely used for aiding surgery in clinical operations, we propose a modeling method for rapid prototyping based on CT image in this paper. Through CT image processing, segmentation, open operation, contour sampling and extraction, the rapid prototyping data interface modal file which is presented as CLI format, can be obtained. Using this method we succeed to operate the replacement of right-side half-pelvis with tumor. In the end, the precision of RP model and construction of data interfaces are also discussed. |
