【摘要】 目的　实现首套中国男、女数字化可视人体结构数据的计算机可视化。方法　在获得首套 (包括 1例男性和1例女性 )数字化可视人体结构数据集 (男性为 2 5 18个横断面 ,总数据量为 90 64 8GB ;女性为 3 64 0个横断面 ,总数据量为13 0 0 4GB)后 ,分别在SGI图像工作站和P4微机上 ,先对二维图像进行处理 ,然后经过在每幅图像上预留的定标点进行对位配准。重建时采用了两种方法 ,一是体绘制 (Volumerendering)重建 ;二是面绘制 (Surfacerendering)重建。结果　在SGI工作站和微机上分别实现了男、女数字化可视人体的整体和局部可视化。并且 ,通过革新三维重建和数据处理技术 ,实现了中国首套数字化人体数据的交互式三维可视化。结论　①经过可视化研究检验 ,本研究组采集的首套中国男、女数字化可视人体数据集符合三维可视化的要求。②本研究建立起来的中国男、女数字化可视人体数据的交互式三维可视化平台 ,形成了数字人体解剖学和虚拟外科手术的雏形。③经过数据分割、分类、配准和绘制重建起来的人体器官或局部模型为在计算机上细致表达人体全身的复杂结构奠定了基础更多还原

【Abstract】 Objective To achieve computer visualization of the first Chinese visible male and female Methods After acquisition of the dataset of the first Chinese visible male and female (2 518 cross sections were obtained from the visible male, the complete data files take up 90 468 GBs; while 3 640 cross sections from the female, the complete data files take up 131 04 GBs ), we processed 2 D images in an SGI Workstation and on P4 computer respectively Then, image registration was performed through reserved scaling point Reconstruction was achieved by two approaches: volume rendering reconstruction and surface rendering reconstruction Results We visualized the whole body and special parts of Chinese visible male and female on an SGI Workstation and a personal computer respectively Furthermore, by optimizing 3 D reconstruction and data processing technique, interactive 3 D visualization of the dataset was achieved Conclusions ①The dataset of the first Chinese visible male and female proves to be eligible for 3 D visualization research ②The platform setup of interactive 3 D visualization of Chinese visible male and female dataset provides foundation for digital human anatomy and virtual surgery ③The models of human organs and parts built through data segmentation, classification, registration and drawing lay basis for rendering complex structures of the whole human body delicately更多还原
