目的  建立国人学龄前男童连续超薄解剖标本数据集，并行可视化应用研究。  方法  选择经64排螺旋CT 和3.0T MRI全身扫描排除器质性病变和畸形的男童标本，6周岁，身高1.14 m，体重23 kg，发育正常，皮肤、内脏无破损，整体无挤压变形。经定型、冷冻及包埋，置于-25 ℃冷库中3周，由山东数字人公司在-25 ℃低温实验室中逐层数控冷冻无锯损铣切，从脚到头0.10 mm铣切,使用Rencay16k3Scanback相机逐层扫描获取高清晰度数据集图像。  结果  共采集11 421张断面图像，所有图像原始保存为PNG格式，每张图像为13 000像素×8000像素，约27.4 MB，整体学龄前男童数据集共计305.60 G。  结论  经文献检索，国内目前尚鲜见有从脚到头完整采集成功的学龄前男童数字化可视人体数据集，成功建立的数字化可视男童数据集，为儿童发育形态研究，各器官虚拟手术入路探索，教材与专著编写及儿童疾病预防、诊治及科普等提供高精度的基础大数据集。

Objective  To establish the continuous ultra-thin anatomical specimen data set of Chinese preschoolers and its application in visualization.   Methods  The boy’s specimens, who was excluded from organic diseases and deformities by 64 row spiral CT and 3.0T MRI, was 6 years old, 1.14 m in height, 23 kg in weight, normal in development, no damage to skin and viscera, and no extrusion deformation as a whole. After three weeks of finalization, freezing, embedding and freezing in -25 ℃ cold storage, Shandong digital human company has milled and cut in -25 ℃ low temperature laboratory layer by layer in numerical control freezing without saw damage, and milled 0.10 mm from the foot to the head. The camera model was rencay16k3 Scanback, which scaned layer by layer to obtain high-definition data set images.   Results  A total of 11 421 cross-section images were collected, all of which were originally saved in PNG format. Each image was 13 000 pixels × 8000 pixels, about 27.4 MB. The total data set of preschool boys was 305.60G.   Conclusion  According to the literature search, there is currently a few complete digital visual human body data set for preschool boys from foot to head. The digital visual boy data set is successfully established in China, which is the study of children’s developmental morphology and various organs will help the exploration of virtual surgery approach, the compilation of teaching materials and monographs, as well as the prevention of children’s diseases, diagnosis and treatment, and popular science.
