摘　　要：目的　探索虚拟中国人 (VCH)高精度建模的关键技术。　方法　 1 建立中国人体标准的评价体系 ,对“虚拟中国人”Ⅰ号及Ⅱ号 (VCHⅠ及VCHⅡ )进行标准化评定 ;完成尸体获取的法律程序 ;2 应用CT、MR和发泡包埋技术对VCHⅠ及VCHⅡ进行切削前预处理 ;3 用动脉灌注的方法对材料的动脉血管进行标记 ;4 用自行设计的冷冻工作间和切削设备对人体材料进行切削和图像采集。　结果　人体材料保持了正常形态 ,预切间距可达到0 1mm ,最小切削间距可达到 0 0 2mm ,可对人体材料进行一次装夹连续切削。Objective To study the key technology of high precision reconstruction of Virtual Chinese Human(VCH). Methods 1\^An evaluation system for Chinese standard human body was established.The cadaver specimens(VCHⅠ and VCHⅡ) were assessed with this system.The law process was acquired to screen the cadavers; 2\^Cadaver specimens of VCH was fixed by using vesicant,and then CT scans and MRI scans were acquired; 3\^Artery perfusion was used to mark the cadaver arteries; 4\^A two\|temperature freezing chamber and cryomacrotome equipment were developed to cryomacrotome and to collect the cutting images. Results The cadaver specimens remained the normal anatomical structure.The cryomacrotom system could shave blocks containing tissues to 0\^1mm interrals in the preliminary experiments.The least interval could reach 0\^02mm.And the serial\|sectioning was done in a fixation without moving the cadaver here to there.Conclusion\ The result of these experiments can improve nowadays cryomacrotome technology in some fields.\;[
