Abstract / Zusammenfassung

Learning anatomy requires identifying, locating and understanding anatomical structures in 3D space. The conventional curriculum includes practical dissection courses on animal cadavers. These practical exercises have shown that many students have trouble translating the 2D images from textbooks into 3D animal bodies [1,2]. In addition, there is a time limit for this demanding learning process: the animal cadavers are only available during the exercises and only in restricted numbers due to safety and hygiene regulations. One of the most demanding topics in veterinary anatomy is to learn the skulls of different species. Therefore, a study is planned to be carried out to examine the effect of annotated 3D scans on the learning success of students, as compared to traditional 2D images. For the creation of the 3D scans the handheld scanners Artec Leo and Artec Space Spider (Artec 3D, Luxembourg [City], Luxembourg) are used. The skulls and half skulls of horses, cattle and pigs are scanned and then uploaded and annotated on Sketchfab (https://sketchfab.com/FUBerlinVeterinaryAnatomy ). The 3D scans can be opened from any device that has internet access. The 3D object can be rotated 360° in any direction, zoomed in and zoomed out. With a mouse click or tap on a specific structure of the 3D scan, the respective annotations are shown to the students. The anatomical structures that have been digitized so far are convincing in terms of geometry, detail, resolution and texture. For the 2022 Winter semester a study with students is planned to test the usability of the 3D scans. The spatial ability will be considered by performing a mental rotation test to see if the struggling students can benefit from this tool. Should an equivalent learning success be achievable, these models could be used to enhance the learning time on the specimen.
