Free Human Anatomy Atlas for Macintosh
RAAViewer is a free program for the Macintosh that allows viewing of labeled images of human anatomy. The labels are linked to a database offering in-depth descriptions of anatomical structures. Image sets are stored in folders and accessed through the program. Many folders of images are included with the download, and you can browse them on your own computer. The download is large because it includes over 1,500 labeled anatomic images.
You may want to download or view the manual first — it is relatively small and will give you a good understanding of the program before committing to the larger download.
Bundled Image Sets
The program is bundled with several sets of images. These include illustrations of the human body published in Eycleshymer & Schoemaker's A Cross-Section Anatomy and photographs of axial slices from the Visible Human Project.
Getting additional sets of images is difficult because of HIPAA restrictions and my current lack of institutional access.
Windows Version
The Windows version is questionable at this time. I do not have ready access to a Windows computer, and since this application was initially launched there have been many changes in that environment — some related to security issues that have increasingly affected the computer world. I would like to upgrade the Windows version, but maintaining the Macintosh version alone has kept my hands full. The Windows version should be considered unsupported. It might still work on older machines, so I have left the download available. (04/16/22)
Terminologia Anatomica
RAAViewer incorporates information from Terminologia Anatomica. If you are interested in this resource independently of RAAViewer, see Terminologia Anatomica. Macintosh users with access to OmniOutliner can download an outline version of Terminologia Anatomica from that page as well.
See the release notes for information on recent additions, and consider downloading the latest version.
