Developing 3D models using photogrammetry for virtual reality training in anatomy

Virtual reality (VR) is an increasingly available resource with numerous applications to medical education, and as a teaching tool has been widely validated in the literature. Photogrammetry, the process of overlapping two-dimensional (2D) photographic images of three-dimensional (3D) objects to create a 3D image or "model," can be used in conjunction with VR to create pedagogically sound learning modules for anatomy education. However, to date, there has not been a detailed description of the process of developing and implementing an in-house VR tool to supplement anatomy instruction. In this article, we examine the methods, benefits, and challenges of using photogrammetry to implement a VR classroom that capitalizes on the strengths of a traditional body donor-based course and the unique strengths of VR. Using off-the-shelf equipment, developing VR content and a VR curriculum is both feasible and approachable for medical educators.
