儿童头部标本薄层断面数据集的建立

Database establishment of children head sample slices

目的以0.1mm层厚建立儿童头部标本薄层断面数据集。方法选择中国8岁男孩头颅一个,处于生长发育高峰前期,发育中等,无重大疾病及畸形。标本经过包埋、固定和冷冻30d后,在山东大学医学院断层影像解剖学研究中心实施数控铣切。铣切层厚:0.1mm;铣切环境:-13℃恒低温实验室。标本铣切完毕,使用佳能EOS-1DS MarkII数码相机进行图像采集。结果整个头部标本共获得图像2 150张,所有原始图像保存格式为RAW,每张图片约20.4MB,共42.87GB大小。再分别转换为PSD格式和JPG格式,用于更广泛的数据分享和交流。结论成功建立了中国儿童头部断层铣切解剖数据集,该数据集铣切层厚为0.1mm,可以为各种儿童头部相关研究提供解剖学基础。

Objective To establish the image database of the digital virtual chinese children craniofacial structure anterior to growth peak time with O. lmm intervals. Methods An 8-year-old anterior to growth peak time, middle growth and no deformity boy skull was selected to establish the visible chinese boy craniofaeial structure image database. After 30 days of embedding, fixing and freezing, the slice-cutting of the skull was performed using a machine in -13~C homothermic cryogenic laboratory in Research Center for Sectional and Imaging Anatomy, Shandong University School of Medicine. The milling was perfomed with 0. I mm at intervals. The Canon EOS-1DS MarkII camera was used to produce all the images. Results All original image data were saved as RAW format, which was transferred to PSD and JPG format for sharing and commumication more generally. The digital virtual chinese children craniofaeial structure dataset gained a total of 2 150 images. An image size with RAW format was approximate of 20. 4MB and the whole craniofacial structure images researched 42. 87GB. We saved 3 versions for variously oriented studies about boy craniofacial structure. Conclusion We established the serial anatomical cross-sectional image data of the eraniofacial structure of the children anterior to growth peak time in succeeded. Compared to other available data, the dataset with at intervals 0. lmm were demonstrated to be of more efficient anatomical information to provide for various related studies of the children craniofacial structures.
