The Benefits of an Augmented Reality Magic Mirror System for Integrated Radiology Teaching in Gross Anatomy
Anatomical Sciences Education, 2019 (bib)

Early exposure to radiological cross-section images during introductory anatomy and dissection courses increases students' understanding of both anatomy and radiology. Novel technologies such as augmented reality (AR) offer unique advantages for an interactive and hands-on integration with the student at the center of the learning experience. In this article, the benefits of a previously proposed AR Magic Mirror system are compared to the Anatomage, a virtual dissection table as a system for combined anatomy and radiology teaching during a two-semester gross anatomy course with 749 first-year medical students, as well as a follow-up elective course with 72 students. During the former, students worked with both systems in dedicated tutorial sessions which accompanied the anatomy lectures and provided survey-based feedback. In the elective course, participants were assigned to three groups and under-went a self-directed learning session using either Anatomage, Magic Mirror, or traditional radiology atlases. A pre- post-test design with multiple choice questions revealed significant improvements in test scores between the two tests for both the Magic Mirror and the group using radiology atlases, while no significant differences in test scores were recorded for the Anatomage group. Furthermore, especially students with low mental rotation test (MRT) scores benefited from the Magic Mirror and Anatomage and achieved significantly higher post-test scores compared to students with a low MRT-score in the theory group. Overall, the results provide supporting evidence that the Magic Mirror system achieves comparable results in terms of learning outcome to established anatomy learning tools such as Anatomage and radiology atlases.
