volume rendering
stereo visualization technology Background
● Anatomy is inherently a 3D problem ● conventional teaching techniques: ○ book -> 2D ○ dissection -> may discourage some students ● Modern technology is underutilized in the classroom Problem Statement
Current State:Students learning anatomy from a textbook, at a low level of excitement, and a low level of exposure to modern imaging modalities
Desired State: Students learning in a stereoscopic anatomy visualization environment, with a high level of excitement, and a high level of exposure to modern imaging modalities
Project Goals: create a fully virtual stereo anatomy viewer
Constraints: budget, pre-designed hardware, must use existing data set Stakeholders
