【摘要】 本文对Ｘ线三维成像和三维显示进行了研究。首先讨论了基于锥形束扫描成像结构的直接体积重建的理论和应用问题，接着形成并实现了基于体积显示的三维显示方法，体积显示在某些特定情形下优于表面显示。结果表明Ｘ线三维成像和三维显示对于应用于临床如计算机辅助手术和医疗评价等的三维影像系统具有重要的价值。更多还原

【Abstract】 X-ray 3D imaging and 3D rendering techniques are investigated in this paper. A study of theory and applications of Direct Volume Reconstruction based On cone-beam scanning geometry is presented.A 3D rendering method with volume rendering is superior to surface rendering in some special situa tions is formulated and implemented. The results show that X-ray 3D imaging and 3D rendering are of important values to 3D image system with clinical applications such as computer-aided surgery, medical evaluation, etc.更多还原
