Stereoscopic Visualization: A Novel Approach to Anatomy Teaching and Procedural Planning

Abstract

Traditional anatomy teaching in medical curricula, particularly in India, relies heavily on cadaveric dissection and two-dimensional diagrams. While these methods provide foundational knowledge, they fail to convey the intricate three-dimensional complexities necessary for understanding anatomical structures in the context of surgical and interventional procedures. Stereoscopic visualisation, which leverages binocular vision to simulate depth perception when adapted for medical education, offers a promising alternative by enhancing spatial understanding of anatomical structures.

The stereoscopic visualisation system, developed collaboratively by the Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST) and Government Engineering College Barton Hill (GECBH), successfully provided 3D visualisations of patient anatomy, enhancing spatial understanding. Key features included real-time processing of CT and MRI data, the ability to visualise large groups simultaneously, and cost-effectiveness. The system allowed for direct visualisation of DICOM files without preprocessing and included customisable features such as windowing techniques and arbitrary plane sectioning. Users reported significant improvements in understanding complex anatomical relationships and planning surgical interventions. Additionally, the system was superior to cadaveric learning for certain visceral anatomies due to its ability to maintain anatomical orientation and spatial relationships. All this makes it a valuable tool in medical education and practice. Despite challenges such as the need for specific software, hardware, and a dark room setup, the system's benefits outweigh these limitations. Future improvements could enhance its capabilities and applicability in medical education and surgical precision. The system thus represents a significant advancement in leveraging stereoscopic technology to bridge the gap between traditional anatomy education and modern clinical requirements
