A complete atlas of the visible human (vh) male cross-sections has been created that is based on the rescans of the original films taken during the vh data collection phase. The resolution of these digitized sections is more than twice as high as that of the most popular first data set. Thus, more detail can be seen. This is important in regions with small structures, e.g. the inner ear. Sections not available in the original data set and missing or damaged parts of images were reconstructed using information from neighboring sections, resulting in 1,878 available cross-sections. This large data set is divided into 35 subsets for easier handling. All digital sections were put on a black background and superfluous areas were cut off. The atlas can be viewed with any internet browser and consists of html pages as well as JPEG images of high quality (24 bits of color for the original sections, 8 bits of gray for the radiological images).
Language independent bars with symbols allow easy navigation. An index page leads to 35 overview pages with icons which are linked to pages showing the sections next to corresponding MR- and CT-images. Transverse MR-images were reconstructed from frontal plane data in all body regions except the head, where the original plane was transverse. Furthermore, 200 sections are labeled in greatest detail in Latin according to the Terminologia Anatomica. Terms are explained in English and German in an additional vocabulary. The full version is available on CD or DVD. A scaled-down version is accessible on http://www.uni-mainz.de/FB/Medizin/Anatomie/workshop/englWelcome.html. The latter version has a lower image compression quality and resolution in order to reduce download time effectively. It replaces the first release of the visible human atlas of the Workshop Anatomy for the Internet (WAI) of the Johannes Gutenberg University of Mainz, Germany.
