Serially sectioned images of whole cadavers have become available through the work of four projects: the Visible Human Project, the Visible Korean, the Chinese Visible Human, and the Virtual Chinese Human (VCH). For the VCH, new techniques and equipment were developed and applied to two female and two male cadavers to overcome some of the limitations noted in previous studies. In this article on the VCH, the procedures described are those used on a male cadaver. The cadaver was young with little to no pathology; there were no flat back artifacts because the cadaver was frozen and embedded in the upright position. Sectioned images (intervals, 0.2 mm) were of exceptional quality and resolution (0.1 mm-sized pixels). Several specific structures were outlined (intervals, 0.6 mm) to acquire segmented images, from which surface models were constructed. The VCH data are to be distributed worldwide and are expected to encourage other investigators to produce useful three-dimensional images and develop interactive simulation programs for clinical practice.
通过四个项目的工作，已经可以获得整个尸体的连续切片图像：可视人项目、可视韩国人、中国人可视人和虚拟中国人（VCH）。对于 VCH，开发并应用了新技术和设备，以克服以前研究中注意到的一些限制，应用于两个女性和两个男性尸体。在这篇关于 VCH 的文章中，所描述的程序是用于男性尸体的。该尸体年轻，几乎没有病理学变化；由于尸体被冷冻并垂直嵌入，因此没有扁平背部伪影。切片图像（间隔 0.2 毫米）质量和分辨率非常出色（0.1 毫米大小的像素）。为了获取分段图像，勾勒出了几个特定的结构（间隔 0.6 毫米），并从中构建了表面模型。VCH 数据将在全球范围内分发，并有望鼓励其他研究人员制作有用的三维图像，并开发用于临床实践的交互式模拟程序。
