Photogrammetry: Adding Another Dimension to Virtual Gross Pathology Teaching.

The article focuses on the use of photogrammetry to create high-quality 3D models of gross veterinary pathological specimens as an innovative teaching tool for undergraduate students during the Covid-19 pandemic. Fresh post-mortem specimens were photographed extensively and digitally reconstructed into life-like 3D models, which were then made accessible via an online platform for self-study and teaching purposes. Student feedback indicated high engagement and improved understanding of lesion distribution and anatomy compared to traditional 2D images. While 3D models cannot fully replace hands-on experience with real specimens, they offer a valuable, accessible resource that preserves rare or perishable material and supports remote and inclusive learning. Limitations include the lack of tactile experience and technical requirements for model creation and visualization.
