Viewing the 3D dataset

Annotated fields are visualised using the JAtlas Viewer program. The viewer contains an Anatomy Tree, listing structures organised by region. In the Anatomy Tree, names of bones can be double-clicked, and 3D objects appear or disappear in the Viewer window. Bones are colour-coded in the Anatomy Key. In the Viewer window, the 3D model of the limb can be rotated and magnified. Sections can be viewed by clicking on View Section from the Viewer window. The 3D Viewer Tutorials (download) provide detailed instructions on using JAtlas Viewer.
