摘　　要：目的构建男性虚拟中国人0.2 mm等间距数字图像数据集,并通过改进人体标本处理工艺,提高“虚拟中国人(男性)”数据集的质量。方法材料选自遗体捐献中心,为食物中毒急性死亡的24岁男性,经石炭酸+朱砂动脉灌注、低温盐水定型、预制冰渣倒立包埋、一次装夹、连续等间距铣削等一系列处理后,采用数码相机照相和计算机自动存储获取数据集。结果共获得分辨率为3 024×2 016象素的断面9232片,TIF格式数据集容量为161.56G。另获JPG格式数据集两个,分别为:分辨率3 024×2 016 像素,容量为8.31 G;分辨率180×120 像素,容量为0.74 G。图像组织边界清晰、肢体变形较小,断面标记明显。结论虚拟中国人男一号(VCH—M1)数据集的质量有进一步的提高,为后续的计算机图像处理和有关应用开发提供了质地优良的基础条件。Objective To establish digitized Virtual Chinese Human Male No.1 (VCH-M1) image dataset with a 0.2-mm equal interval. Methods The body of a 24-year-old male was used for this study. Perfusion with phenol and vermilion of the arteries was performed, followed by body shape adjustment by cold saline and pre-embedding with broken ices in an upside-down position, which was completed in a stepwise procedure to minimize body shape deformation. Section milling was conducted subsequently with the section thickness of 2 mm and the section images were captured by digital camera, which were immediately transferred to a computer for storage and processing. Results A total of 9 232 sections were obtained for the whole body, and the resolution of each of the image in TIF format was 3 024×2 016 pixels, resulting in the size of approximately 18 M for each image and about 161 G for the whole dataset. Conclusions Compared with VCH-F1, the image quality in VCH-M1 dataset is significantly improved, demonstrated by much clearer tissue boundary in the images and minimized body shape deformation during the embedding process.
