[[File:CT presentation as thin slice, projection and volume rendering.jpg|thumb|Types of presentations of [[CT scan]]s, with two examples of volume rendering]]
Volume rendering is distinguished from thin slice [[tomography]] presentations, and is also generally distinguished from projections of 3D models, including [[maximum intensity projection]].<ref name="FishmanNey2006">{{cite journal|author-link1=Elliot K.
