The sectioned images and surface models of a cadaver head in the Visible Korean Project would be more beneficial if they were accessible and informative. To this aim, 3 policies were established: (1) the data are promptly obtainable and observable; (2) the graphic data are accompanied by explaining the anatomic terms; and (3) two-dimensional images and three-dimensional models are shown together. According to the policies, the following were attempted. Two hundred thirty-five couples of sectioned images and outlined images (intervals, 1 mm) of the head were prepared. Browsing software was developed where the 2 corresponding images were displayed simultaneously. In addition, the structures in the images were recognized with the aid of automatic labeling. From the outlined images, surface models of 178 head structures were constructed. The two-dimensional surface models including the sectioned images were embedded into the three-dimensional surface models. All the models were categorized into systems and arranged to be inputted to a PDF (portable document format) file. The finalized PDF file containing comprehensive head data could be explored on Adobe Reader. If the user clicked on the surface models, their anatomic names were highlighted. The sectioned images, outlined images, and surface models in the browsing software and PDF file can be downloaded from the homepage (anatomy.co.kr) free of charge. The state-of-the-art graphic information will hopefully assist medical students in learning head anatomy. In addition, the raw data are expected to contribute to the various clinical practice simulations.
