The use of 3D models to understand complex human anatomic structures has received more and more attention as technology improves. The ventricles of the brain are comprised of a communicating network of cavities, which include two lateral ventricles, a third ventricle within the diencephalon, and a fourth ventricle within the brainstem. Using computed tomography arteriogram (CTA) images of the head, anatomic structures of the brain were manually segmented using surface rendering display of the CTA images Image segmentation was facilitated by use of a Wacom pen and tablet. Amira software version 5.6 was used to develop the 3D models of the ventricles and brain stem. The axial, sagittal, and coronal images of the brain were used in tandem to provide a holistic view for segmentation. The 3D virtual models of the ventricles and brainstem can then be presented stereoscopically to show spatial relationships between the ventricle cavity space and the brainstem with a stereoscopic view via polarized 3D glasses. These structures can be rotated through 360 degrees in all axes, and can be zoomed in and zoomed out. 3D models like these help students understand the complex spatial relationships between the ventricles and brainstem that are otherwise difficult to visualize in traditional, 2D textbook images.
