【摘要】 为了突出人体重点器官的显示 ,提出了一种新颖的基于混合数据场的快速体绘制算法 .从原始的三维数据场中提取重要的结构 ,然后将原始三维数据中非重点的部分转换为梯度数据 ,构成混合数据 .从而对混合数据进行体绘制 .结果表明该算法可以加快体绘制速度同时改善重点器官的显示效果更多还原

【Abstract】 In order to display important organs outstandingly, a new approach for fast volume rendering algorithm based on mixed data sets was put forward. Important organs were extracted from original 3D data sets. Some general original data sets were transformed into gradient data sets to produce mixed data sets. And volume rendering of mixed data was processed. It was shown that the algorithm accelerated rendering and improved the display of important organs.更多还原
