摘要

为了解决临床构建美观合适的眶假体模型的难题，本文分别提出了基于体积切割和表面切割的两种方法。利用样条插值、区域生长、三角补片计算、圆柱切割等技术，获得了尺寸合适、边缘光滑的三维眶假体模型。此外，在假体构建过程中加入视觉反馈机制，使假体模型更好地贴合缺陷部位。结果表明，本文基于CT图像的三维眶假体模型构建方法显著提高了临床可接受性和有效性。

CT image based 3D orbital prosthesis model construction method

To solve the clinical problem of constructing an aesthetic and appropriate orbital prosthesis model, two methods based on volume cutting and surface cutting respectively are proposed in this paper. Using spline interpolation, region growth, triangular patch calculation, cylinder cutting and other techniques, we obtain the 3D orbital prosthesis model with a proper size and smooth edges. Besides, a visual feedback mechanism is added in the process of prosthesis construction to make the prosthesis model fit the defect part better. The results show that the CT image based 3D orbital prosthesis model construction method in this paper significantly improves the clinical acceptability and effectiveness.
