1- Open Anatomy Browser (OABrowser)
The Open Anatomy Browser is a web tool created by Harvard that lets users explore 3D anatomical models. It shows detailed views of body structures through both 3D models and cross-sections. Doctors, students, and researchers can use it to study anatomy interactively and share their knowledge with others.
The tool is open-source and available online at Open Anatomy.
The Open Anatomy Project is an initiative led by Brigham and Women's Hospital in Boston, aiming to make comprehensive digital anatomy atlases freely accessible to everyone. Current commercial atlases are often expensive and limited, preventing many students, doctors, and the public from accessing essential anatomical knowledge.
The source-code is available on Github.
