Anatomy teaching methods have used traditional simulated 3D computer models. However, these 3D models have usually been limited to normal anatomy, using computer screen‐based rotating models. We have recently established a virtual 3D anatomy workstation for creating and presenting stereoscopic 3D virtual models. These models were developed using Amira, a powerful software package for bioscience research that anatomists can use to create 3D structures from slice data. We used computed tomography arteriogram (CTA) images to reconstructed 3D virtual models. The virtual models are presented stereoscopically in a virtual reality environment and can be rotated through 360 degrees in all axes, and can be made larger or smaller. Flexible views of internal structures are possible. Students wear polarized 3D glasses and sit in a small theater‐like classroom with dim light background. Images were virtually displayed in stereo mode, and structures were shown as flowing in the center of the room in front of each student, similar to watching a 3D movie in a theater. The stereoscopic 3D models allow students to view normal variations of cerebral vasculature and abnormalities, such as aneurysms, from many different angles and in greater detail than is possible using flat, 2D images.
