Using Augmented Reality to Enhance Biomedical Pathology Dissection Guides

In recent years, researchers have begun to explore extended reality’s use in education. Several universities have implemented visualization tablets and virtual reality applications to learn about human anatomy.  Researchers have found that extended reality has a greater impact on spatial learning than traditional 2D textbooks and videos. Although there is plenty of research for medical students, there is a distinct lack of high-quality research regarding Augmented Reality for teaching biomedical and pathology technician students.  Several developments have been made to augment books. Taking this approach, the aim of this thesis was to develop an application to augment the Royal College of Pathologist dissection guide on nephrectomies.

A series of 3D kidney models which were segmented in 3D Slicer from a computerized tomography (CT) scan were then imported into 3DS Max and ZBrush for retopology, texturing, and animation. The application utilized augmented reality with image targets and a series of model controls which allowed the user to animate the models and provide information in a clear, intuitive format for amateurs following along the dissection guide. Following the application development, user testing was done utilizing a standardized survey called the System Usability Scale.This provided valuable user insight and feedback into the application which demonstrated that the application was fully functional and easy to use for a novice.
