Abstract
This paper outlines an approach to create stereoscopic 3D computer graphics for visualization of epidural insertions. The graphics are built from several 3D vertex models of the anatomical structures including the vertebrae, tissue layers and the skin, subcutaneous fat, supraspinous ligament, interspinous ligament, ligamentum flavum and epidural space. The 3D models are wrapped with full color textures and vertex edges are rounded. The objects are stored in object files and are rendered as 3D by a custom OpenGL application. Graphics drivers calculate the angles and offset for the two separate stereo images and render both in 3D. The stereoscopic images are viewed through a visor containing two OLED microdisplays in stereo using the page-flipped method. The completed stereo simulation allows depth to be perceived so that the operator can judge depth of the needle tip in relation to tissue layers and bones, which aids to the location of the epidural space. Applying stereoscopic vision to epidural simulators will help the operator to visualize the depths required for correct needle placement in the epidural space. Copyright © 2012 by ASME.
