摘要:
目的 建立合适的人体器官三维数字化模型,为辐射剂量计算打下基础。方法 采用符合4项准则的轮廓线重建算法建立人体器官三维数字化模型。先提取器官的轮廓,然后进行表面重建,最后通过合适的光照和法线求取、法线平均等处理,得到表面平滑、结构准确、可视性强的三维重建图像。结果和结论 采用本文的方法,成功重建了人体多个器官的三维数字化模型。该方法适合于人体器官三维模型的建立,能满足剂量计算的需要。
Abstract:
Objective To build proper three-dimensional models of human organs for radiation dose calculation. Method Human organ models were built by contour reconstruction algorithm conforming to 4 criteria. The contours of the organs were extracted based on the contours of the reconstructed organ surfaces, and the three-dimensional models with smooth surface, exact structure and good visibility were completed by computer graphic techniques such as lighting, smoothing, and normal average. Result and Conclusion Several organ models were successfully reconstructed, suggesting that this method is suitable for building three-dimensional digital human organ models whith can meet the need for dose calculation.
