The ACS "Whole Frog" project is intended to introduce the concepts of modern, computer based 3D visualization, and at the same time to demonstrate the power of whole body, 3D imaging of anatomy as a curriculum tool. The goal of the Whole Frog Project is to provide high school biology classes the ability to explore the anatomy of a frog by using data from high resolution MRI imaging and from mechanical sectioning, together with 3D surface and volume rendering software to visualize the anatomical structures of the intact animal. Ultimately we intend to be able to "enter the heart and fly down blood vessels, poking our head out at any point to see the structure of the surrounding anatomy".
