目的建立虚拟中国人男性一号血管灌注循环系统的三维模型,为解剖教学以及临床虚拟手术研究提供三维数据模型。方法对数字虚拟中国人男性一号样本进行血管灌注,对获取的彩色断层图片进行空间配准和半自动交互分割,对分割后的数据通过并行算法进行快速三维重建处理。结果对灌注后的动静脉血管和心脏建立了三维模型;通过组合动脉和静脉以及心脏模型获得了全身循环系统的三维模型,弥补了数字化虚拟人体血管模型的空白。结论经过样本的动脉灌注处理之后,在获取高分辨率的切片数据的基础上,建立了精确、完整的血管模型。

Objective Three-dimensional digital structure modeling of human perfused blood vessels for anatomyteaching and virtual clinic surgery. Methods High-resolution and color cryo-sections datasets were acquired withperfused arteries on the Visual Chinese Human Male-No.1. To make the images of datasets dimensional registered and theblood vessel was segmented and classified interactively. The segmented data was reconstructed with parallelismalgorithm. Result The three-dimension structure models of the arteries, veins and heart were established. The modelsof the whole cardiovascular system of Visual Chinese are integrity and real represented for blood vessels perfusion.Conclusion Based on the high-resolution images of VCH cryo-sections and perfusion of artery, the integrity andaccurate human blood vessel models has been constructed.
