【摘要】 提出了一种基于纹理映射的体绘制算法,提高了图像的重建效率,增强了图像的重建效果。算法实现了对二维医学图像序列的三维重建,在目前通用的个人计算机上可以以近似实时的速度重建出高质量的三维图像。针对算法中存在的问题提出了两种不同的改进方法,取得了较好的效果。结合纹理生成的过程和纹理重采样的过程,对重建后的三维图像实现了交互切割的算法。更多还原

【Abstract】 A new method of volume rendering based on texture mapping is presented. The technique significantly improves both performance and image quality of the 3D reconstruction. The method realizes 3D reconstruction for 2D medical images sequence. On commodity PC, can be obtained by the proposed method. high image quality at a rate near realtime. For visual artifacts in texture mapping, two improved methods are presented. Considering the processes of making texture and resampling, the method of interactive incise for 3D image is realized.更多还原
