Visible Human Project (VHP)' was initiated by US National Library of Medicine in 1989, and in August 1991, the library signed a contract with Health Science Center of the University of Colorado to formally carry out the project. Accordingly, research team at the University of Colorado collected a structural data set of human body after obtaining successive sectional images. A digital image data set of a complete human male cadaver was acquired and made available for public use in November 1994, which aroused worldwide enthusiasm in this field, and remarkable social and economic benefit has been gained. Thereafter, some countries initiated their visible human project one after another. Korea started 5-year' Visible Korean Human (VKH)' project (Mar. 2000-Feb. 2005) in 2000, and the first data set derived from a patient with cerebroma was acquired in 2001. China began its project in 1999. The first data set of Chinese visible human was obtained at The Third Military Medical University in October 2002. Before that, by utilizing data made public by US VHP, Chinese scientists in informatics had exerted themselves on preliminary work to pave the way for further achievement. Now that VHP research is such a promising scientific field to meet the need of digital era and will be increasingly common in many areas related with structure and function of human body, the deployment of Chinese Visible Human Project (CVHP) is of great strategic significance with regard to science and technology. 展开更多
