Project Description

Challenges in teaching veterinary anatomy include reducing the number of cadavers, preparation time, and budget. Access to specimens can be limited and costly. 3D prints can be transported internationally whereas biological materials encounter restrictions. The purpose of this study was to collaborate with the SGU School of Veterinary Medicine to compare  the anatomical accuracy and cost of photogrammetry, 3D scanning, and CT scan data in creating 3D teaching models of the equine phalanges. Veterinary anatomists evaluated the accuracy of osteological landmarks by comparing original bone specimens to the 3D prints. The purpose of the display is to guide the audience in determining which method is best suited for their own project by showcasing the P3 (distal) phalanx for visual and tactile comparison. The research demonstrates that photogrammetry is an accurate and cost-effective technique that rivals the quality of detail captured through Artec 3D scanning and CT volumetric rendering.
