A Novel Three-Dimensional Interactive Virtual Face to Facilitate Facial Anatomy Teaching Using Microsoft HoloLens

Recent changes in curriculum have seen a curtailment in the time devoted to the teaching of gross anatomy, one of the most integral components of medical education. This has resulted in the reduction, and in some cases the elimination of cadaveric dissection, most significantly due to the huge amount of resources involved in conducting a cadaveric dissection program. Nevertheless, cadaveric dissection still comprises a significant part of the time devoted to the teaching of gross anatomy. Hence it is of paramount importance that maximum benefit be derived from cadaveric dissections since it offers unique advantages, most significant being the appreciation of the three-dimensional concepts of body organization. The key part of effective anatomy teaching using cadaveric dissection is having the best instructors for this task. While student evaluation of teaching (SET) questionnaires have been used to evaluate instructor proficiency in lecture classes, there is no SET questionnaire that has been specifically designed for the assessment of instructors involved in cadaveric dissection. The aim of this article is to design a questionnaire specifically for the evaluation of the competency of instructors involved in cadaveric dissection, and reinforce the arguments for the continued use of cadaveric dissection in the teaching of anatomy.

Abstract The purpose of this study was to develop and demonstrate a novel imaging platform that post-processes volumetric imaging data (e.g. Computed Tomography (CT) or Magnetic Resonance angiography) to provide holographic visualization for pre-procedural treatment planning of a morphologically complex brain aneurysm. Digital CT images were segmented, using the Materialise Mimics software, into three-dimensional digital models that were imported into a prototype application for the Microsoft HoloLens. Feedback from testing the prototype indicated potential for augmented reality to assist an interventionalist in spatial understanding and depth perception of spatially complex anatomy and could increase confidence in pre-procedural planning. Future studies will be conducted with additional cases to further validate the utility of the platform in surgical planning decisions and to expand the platform for patient/resident education, telemedicine, and intra-operative use.

Enhance Patient Care

AbstractAugmented reality (AR) and virtual reality (VR) are burgeoning technologies that have the potential to greatly enhance patient care. Visualizing patient-specific three-dimensional (3D) imaging data in these enhanced virtual environments may improve surgeons’ understanding of anatomy and surgical pathology, thereby allowing for improved surgical planning, superior intra-operative guidance, and ultimately improved patient care. It is important that radiologists are familiar with these technologies, especially since the number of institutions utilizing VR and AR is increasing. This article gives an overview of AR and VR and describes the workflow required to create anatomical 3D models for use in AR using the Microsoft HoloLens device. Case examples in urologic oncology (prostate cancer and renal cancer) are provided which depict how AR has been used to guide surgery at our institution.

Abstract – Augmented reality (AR) technology facilitates augmentation of current views with digital artifacts, such as information, three-dimensional objects, audio, and video. Mixed reality (MR) represents an enhanced version of AR, where advanced spatial mapping is used to anchor digital artifacts in physical space. Using MR technology, digital artifacts can be more closely integrated into the natural environment, thereby transcending physical limitations and creating enhanced blended learning environments. In this paper, we propose an approach for integration of MR technology into engineering education. Specifically, we propose to integrate Microsoft HoloLens into a first-year course on data structures and algorithms to improve student engagement and learning outcomes. In the pilot study, students were assigned to implement A* algorithm and then given a chance to visualize their implementation using Microsoft HoloLens. The feedback provided by students indicated increased engagement and interest in graph-based path-finding algorithms as well as MR technology.

AbstractObjectives:(1) To investigate the efficacy of a computer-generated three-dimensional laryngeal model for laryngeal anatomy teaching; (2) to explore the relationship between students' spatial ability and acquisition of anatomical knowledge; and (3) to assess participants' opinion of the computerised model.Subjects and methods:Forty junior doctors were randomised to undertake laryngeal anatomy study supplemented by either a three-dimensional computer model or two-dimensional images. Outcome measurements comprised a laryngeal anatomy test, the modified Vandenberg and Kuse mental rotation test, and an opinion survey.Results:Mean scores ± standard deviations for the anatomy test were 15.7 ± 2.0 for the ‘three dimensions’ group and 15.5 ± 2.3 for the ‘standard’ group (p = 0.7222). Pearson's correlation between the rotation test scores and the scores for the spatial ability questions in the anatomy test was 0.4791 (p = 0.086, n = 29). Opinion survey answers revealed significant differences in respondents' perceptions of the clarity and ‘user friendliness’ of, and their preferences for, the three-dimensional model as regards anatomical study.Conclusion:The three-dimensional computer model was equivalent to standard two-dimensional images, for the purpose of laryngeal anatomy teaching. There was no association between students' spatial ability and functional anatomy learning. However, students preferred to use the three-dimensional model.
