The first image above is of a human knee and was prepared from MRI scans and photographs of thin slices of a cadaver's knee at the University of Colorado Center for Human Simulation as part of the 3D Visible Human Project. The original images were made available courtesy of Dr. Karl Reinig and Paul Sommer. The second image is a Hubble Space Telescope picture of the nearby galaxy M100, as photographed with the Wide-Field Planetary Camera 2 (WFPC2). A simulation of a detonating supernova was added by Donald Gudehus. Supernovae have a rapid rise (in a day or so) in their light output and a gradual decline (over many weeks to several months) as the remains of the exploded star gradually cool. The third image is magnetic resonance angiogram of the Circle of Willis, the termination of the Basilar and Internal Carotids, which comprise the system of arteries which conduct blood to the brain. The Circle of Willis is located on the floor of the cranial cavity, and loops around the brainstem. The original images were made available courtesy of Dr. Marijn Brummer of the Department of Radiology at the Emory University School of Medicine. These images are additional examples of what can be printed on lenticular screens.
