National Library of Medicine Visible Human Project - has created publicly-available complete, anatomically detailed, three-dimensional representations of a human male body and a human female body. The data sets were designed to serve as (1) a reference for the study of human anatomy, (2) public-domain data for testing medical imaging algorithms, and (3) a test bed and model for the construction of network-accessible image libraries. The VHP data sets have been applied to a wide range of educational, diagnostic, treatment planning, virtual reality, artistic, mathematical, and industrial uses. About 4,000 licensees from 66 countries were authorized to access the datasets. As of 2019, a license is no longer required to access the VHP datasets. https://www.nlm.nih.gov/research/visible/visible_human.html
