“…8,22,23 Most photogrammetry studies propose models of varying precision using techniques that require a dedicated platform and investment. 9,24 Some have already suggested the use of smartphones, 21,24,25 but, to our knowledge, no study to date has proposed a combination of smartphone photogrammetry of real specimens and stereoscopic techniques nor challenged the photogrammetry with a testing phantom. In addition to the quality of the models obtained, the strength of the technique presented here lies in its simplicity and low cost.…”

Traditional teaching methods struggle to convey three‐dimensional concepts effectively. While 3D virtual models and virtual reality platforms offer a promising approach to teaching anatomy, their cost and specialized equipment pose limitations, especially in disadvantaged areas. A simpler alternative is to use virtual 3D models displayed on regular screens, but they lack immersion, realism, and stereoscopic vision. To address these challenges, we developed an affordable method utilizing smartphone‐based 360° photogrammetry, virtual camera recording, and stereoscopic display (anaglyph or side‐by‐side technique). In this study, we assessed the feasibility of this method by subjecting it to various specimen types: osteological, soft organ, neuroanatomical, regional dissection, and a dedicated 3D‐printed testing phantom. The results demonstrate that the 3D models obtained feature a complete mesh with a high level of detail and a realistic texture. Mesh and texture resolutions were estimated to be approximately 1 and 0.2 mm, respectively. Additionally, stereoscopic animations were both feasible and effective in enhancing depth perception. The simplicity and affordability of this method position it as a technique of choice for creating easily photorealistic anatomical models combined with stereoscopic depth visualization.

Photogrammetry is technique which allows generation of three-dimensional models using photographic images. It is relatively new technique and very rarely used, as for now, in anatomy, but in our opinion, it has a great potential for being great alternative for conventional anatomy teaching methods. In the anatomy department of Wroclaw Medical University, we decided to check usefulness of this method as it comes to generation of anatomical models. In process we came up with a very simple, yet effective way of taking photos and generating models sufficient for didactics. We based our technique on very accessible and user-friendly mobile phone apps, basic medical-grade lamp setup, mobile phone cameras, and free computer software. All that makes our technique easy, fast, and cheap – which makes this method a better, potentially widely available alternative for conventional learning materials. We are sure photogrammetry will become more and more popular because of its superiority to digital anatomical resources such as three-dimensional atlases. Additionally, we can see a rise in popularity of technologies such as VR (virtual reality) and AR (augmented reality), which can be useful in further implementation and development of photogrammetric 3D anatomical models as studies have shown.
