OBJECTIVE
To establish digitized virtual Chinese No.1 female (VCH-F1) image database.
METHODS
A 19 years old female cadaver was scanned by CT, MRI, and perfused with red filling material through formal artery before freezing and em- bedding. The whole body was cut by JZ1500A vertical milling machine with a 0.2 mm inter-spacing. All the images was produced by Fuji FinePix S2 Pro camera.
RESULTS
The body index of VCH-F1 was 94%. We cut 8 556 sections of the whole body, and each image was 17.5 MB in size and the whole database reached 149.7 GB. We have totally 6 versions of the database for different applications.
CONCLUSIONS
Compared with other databases, VCH-F1 has good representation of the Chinese body shape, colorful filling material in blood vessels providing enough information for future registration and segmentation. Vertical embedding and cutting helped to retain normal human physiological posture, and the image quality and operation efficiency were improved by using various techniques such as one-time freezing and fixation, double-temperature icehouse, large-diameter milling disc and whole body cutting.
目的
建立数字化中国女性1号（VCH-F1）虚拟图像数据库。
方法
对一具19岁女性尸体进行CT、MRI扫描，并在冷冻和包埋前通过正规动脉灌注红色填充材料。用JZ1500A立式铣床以0.2毫米的间距对全身进行切割。所有图像均由富士FinePix S2 Pro相机拍摄。
结果
VCH-F1的身体指数为94%。我们对全身切割了8556个切片，每个图像大小为17.5MB，整个数据库达到149.7GB。我们共有6个版本的数据库用于不同应用。
结论
与其他数据库相比，VCH-F1对中国人体型有良好的呈现，血管内彩色填充材料为未来的配准和分割提供了足够信息。垂直包埋和切割有助于保持人体正常生理姿势，通过一次性冷冻固定、双温冰库、大直径铣盘和全身切割等多种技术提高了图像质量和操作效率。
