Advanced features of whole body sectioned images: Virtual Chinese Human



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.
