Although cadavers constitute the gold standard for teaching anatomy to medical and health science students, there are substantial financial, ethical, and supervisory constraints on their use. In addition, although anatomy remains one of the fundamental areas of medical education, universities have decreased the hours allocated to teaching gross anatomy in favor of applied clinical work. The release of virtual (VR) and augmented reality (AR) devices allows learning to occur through hands‐on immersive experiences. The aim of this research was to assess whether learning structural anatomy utilizing VR or AR is as effective as tablet‐based (TB) applications, and whether these modes allowed enhanced student learning, engagement and performance. Participants (n = 59) were randomly allocated to one of the three learning modes: VR, AR, or TB and completed a lesson on skull anatomy, after which they completed an anatomical knowledge assessment. Student perceptions of each learning mode and any adverse effects experienced were recorded. No significant differences were found between mean assessment scores in VR, AR, or TB. During the lessons however, VR participants were more likely to exhibit adverse effects such as headaches (25% in VR P < 0.05), dizziness (40% in VR, P < 0.001), or blurred vision (35% in VR, P < 0.01). Both VR and AR are as valuable for teaching anatomy as tablet devices, but also promote intrinsic benefits such as increased learner immersion and engagement. These outcomes show great promise for the effective use of virtual and augmented reality as means to supplement lesson content in anatomical education.

Augmented reality (AR) has recently been utilized as an integrative teaching tool in medical curricula given its ability to view virtual objects while interacting with the physical environment. The evidence for AR in medical training, however, is limited. For this reason, the purpose of this mixed method study was to evaluate the implementation of overlaying donor-specific diagnostic imaging (DSDI) onto corresponding body donors in a fourth-year, dissection-based, medical elective course entitled anatomy for surgeons (AFS). Students registered in AFS course were separated into groups, receiving either DSDI displayed on Microsoft HoloLens AR head-mounted display (n = 12) or DSDI displayed on iPad (n = 15). To test for the change in spatial ability, students completed an anatomical mental rotation test (AMRT) prior to and following the AFS course. Students also participated in a focus group discussion and completed a survey at the end of AFS, analyzed through thematic triangulation and an unpaired, Mann Whitney U test respectively, both addressing dissection experience, DSDI relevancy to dissection, and use of AR in anatomical education. Although statistically significant differences were not found when comparing student group AMRT scores, survey and discussion data suggest that the HoloLens had improved the students' understanding of, and their spatial orientation of, anatomical relationships. Trunk dissection quality grades were significantly higher with students using the HoloLens. Although students mentioned difficulties with HoloLens software, with faculty assistance, training, and enhanced software development, there is potential for this AR tool to contribute to improved dissection quality and an immersive learning experience.  相似文献

For centuries cadaveric dissection has been a cornerstone of medical anatomy education. However, time and financial limitations in modern, compressed medical curricula, coupled with the abundance of alternate modalities, have raised questions about the role of dissection. This study was designed to explore student perceptions of the efficacy of a dissection program for learning musculoskeletal anatomy, and possible adaptations for appropriate inclusion of dissection in the modern medical curricula. A paper-based questionnaire was used to collect data from 174 medical students after completion of cadaveric dissections. Data were analyzed using both quantitative and qualitative methods. Students strongly believed that cadaver-based learning is essential to anatomy education and modern teaching modalities only complement this. Moreover, most students reported that dissection provided an additional, immersive learning experience that facilitated active learning and helped in developing manual competencies. Students with previous dissection experience or an interest in anatomy-related specialties were significantly more likely to attend dissection sessions. Students found that the procedural dissection components enhanced the knowledge of applied anatomy and is beneficial for the development of clinical skills. They welcomed the idea of implementing more procedure-based dissections alongside lectures and prosections-based practical (PBP) sessions. Cadaveric dissection plays an integral role in medical anatomy education. Time restraints and an increased focus on clinical significance, however, demand carefully considered adaptations of existing dissection protocols. The introduction of procedure-based dissection offers an innovative, highly engaging and clinically relevant package that would amalgamate skills essential to medical practice while retaining the benefits that have allowed dissection to stand the test of time.  相似文献

There is increasing use of computer–based resources to teach anatomy, although no study has compared computer‐based learning to traditional. In this study, we examine the effectiveness of three formats of anatomy learning: (1) a virtual reality (VR) computer‐based module, (2) a static computer‐based module providing Key Views (KV), (3) a plastic model. We conducted a controlled trial in which 60 undergraduate students had ten minutes to study the names of 20 different pelvic structures. The outcome measure was a 25 item short answer test consisting of 15 nominal and 10 functional questions, based on a cadaveric pelvis. All subjects also took a brief mental rotations test (MRT) as a measure of spatial ability, used as a covariate in the analysis. Data were analyzed with repeated measures ANOVA. The group learning from the model performed significantly better than the other two groups on the nominal questions (Model 67%; KV 40%; VR 41%, Effect size 1.19 and 1.29, respectively). There was no difference between the KV and VR groups. There was no difference between the groups on the functional questions (Model 28%; KV, 23%, VR 25%). Computer‐based learning resources appear to have significant disadvantages compared to traditional specimens in learning nominal anatomy. Consistent with previous research, virtual reality shows no advantage over static presentation of key views. Anat Sci Educ 6: 211–215. © 2013 American Association of Anatomists.  相似文献

The aim of this study was to investigate the effect of immersive three-dimensional (3D) interactive virtual reality (VR) on anatomy training in undergraduate physical therapy students. A total of 72 students were included in the study. The students were randomized into control (n = 36) and VR (n = 36) group according to the Kolb Learning Style Inventory, sex, and Purdue Spatial Visualization Test Rotations (PSVT-R). Each student completed a pre-intervention and post-intervention test, consisting of 15 multiple-choice questions. There was no significant difference between the two groups in terms of age, sex, Kolb Learning Style Inventory distribution, and the PSVT-R (P > 0.05). The post-test scores were significantly higher compared to pre-test scores in both the VR group (P < 0.001) and the control group (P < 0.001). The difference between the pre-test and post-test results was found to be significantly higher in favor of the VR group (P < 0.001). In this study, anatomy training with a 3D immersive VR system was found to be beneficial. These results suggest that VR systems can be used as an alternative method to the conventional anatomy training approach for health students.  相似文献

The author investigated the interaction effect of immersive virtual reality (VR) in the classroom. The objective of the project was to develop and provide a low-cost, scalable, and portable VR system containing purposely designed and developed immersive virtual learning environments for the US Army. The purpose of the mixed design experiment was to compare lecture-based and immersive VR-based multimedia instruction, in terms of declarative knowledge acquisition (i.e. learning) of basic corrosion prevention and control with military personnel. Participants were randomly assigned to the control group (N?=?115) or investigational group (N?=?25) and tested immediately before and after training. The author accessed learning outcomes from the pre-exam and post-exam scores and VR system usability from exit questionnaires. Results indicate that both forms of instruction will increase learning. VR-based did produce higher gain scores and there was a statistically significant interaction between instruction type and time.  相似文献

Advanced technologies have been widely applied in medical education, including human-patient simulators, immersive virtual reality Cave Automatic Virtual Environment systems, and video conferencing. Evaluating learner acceptance of such virtual reality (VR) learning environments is a critical issue for ensuring that such technologies are used to greatest effect. This research describes the use of high performance real-time interactive software (VR4MAX) to build a prototype 3D VR learning system. A questionnaire survey was distributed to 167 university students to investigate learner attitudes toward learning via VR applications. Experimental results show that immersion and imagination features of VR-mediated course contents have a positive impact on perceived usefulness, and can also predict perceived ease of use, both of which contributors to behavioral intention of learners to use VR learning systems. Overall, this research validates the relationship between three features of VR and learners' behavioral intention to use VR learning. The results could prove helpful in guiding future research related to VR learning.  相似文献

ABSTRACT

Observation training of home dental practice is easily influenced by the site and time, and differences in learning content are likely to occur among students. The aim of the present study is to prototype virtual reality (VR) teaching material for home dental practice to provide dental students with the chance to observe patients receiving home dental care. The VR teaching material was created before the study, using a patient’s home as the medical treatment scene, and practical training was then conducted using this VR teaching material with dental students. To examine its educational effectiveness, 101 dental students, who attended practical training between June 2018 and January 2019, responded to survey questions before and after watching the VR teaching material. They took a comparative examination, based on the questionnaire results, using text mining and hierarchical cluster analysis. Two variables were tested: changes in self-confidence regarding knowledge of home dental practice (knowledge confidence) and changes in self-confidence regarding treatment assistance (assistance confidence). There was a significant increase in student’s knowledge confidence and assistance confidence scores (p < .001). Moreover, hierarchical cluster analysis indicated a change in the cluster before and after they watched the VR teaching material. Given that VR teaching material makes it possible to conduct home observation training for a variety of reasons, such as lack of available facilities or patient reservation issues, the findings indicate that VR teaching material can supplement dental students’ training in home dental practice.  相似文献

Increasing number of medical students and limited availability of cadavers have led to a reduction in anatomy teaching through human cadaveric dissection. These changes triggered the emergence of innovative teaching and learning strategies in order to maximize students learning of anatomy. An alternative approach to traditional dissection was presented in an effort to improve content delivery and student satisfaction. The objective of this study is to acquire three-dimensional (3D) anatomical data using structured-light surface scanning to create a dynamic four-dimensional (4D) dissection tool of four regions: neck, male inguinal and femoral areas, female perineum, and brachial plexus. At each dissection step, identified anatomical structures were scanned using a 3D surface scanner (Artec Spider™). Resulting 3D color meshes were overlaid to create a 4D (3D+time) environment. An educational interface was created for neck dissection. Its implementation in the visualization platform allowed 4D virtual dissection by navigating from surface to deep layers and vice versa. A group of 28 second-year medical students and 17 first-year surgery residents completed a satisfaction survey. A majority of medical students (96.4%) and 100% of surgery residents said that they would recommend this tool to their colleagues. According to surgery residents, the main elements of this virtual tool were the realistic high-quality of 3D acquisitions and possibility to focus on each anatomical structure. As for medical students, major elements were the interactivity and entertainment aspect, precision, and accuracy of anatomical structures. This approach proves that innovative solutions to anatomy education can be found to help to maintain critical content and student satisfaction in anatomy curriculum.  相似文献

Virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR) are examples of immersive technologies that have the potential to improve medical practice and education. As a result, they have recently sparked much research interest. However, there are few reviews related to the use of immersive technologies (including VR, AR, MR, and XR) in medical practice and education. Remarkably, six research questions related to the trends, application areas, recipients, teaching contents, evaluation methods, and performance remain unanswered. To this end, this study conducts a systematic review to analyse 128 articles from 2012 source papers, all of which are indexed in the Web of Science. The review results indicate that immersive technology is currently used primarily on surgery and anatomy-related subjects for doctors, medical students and interns. Furthermore, group experiments are the most commonly used data collection method. The results provide insights into the current research trends related to immersive technology applications for medical practice and education. They also serve as an essential reference for scholars in the medical practice and education contexts.  相似文献

Despite a long tradition, conventional anatomy education based on dissection is declining. This study tested a new virtual reality (VR) technique for anatomy learning based on virtual contrast injection. The aim was to assess whether students value this new three‐dimensional (3D) visualization method as a learning tool and what value they gain from its use in reaching their anatomical learning objectives. Several 3D vascular VR models were created using an interactive segmentation tool based on the “virtual contrast injection” method. This method allows users, with relative ease, to convert computer tomography or magnetic resonance images into vivid 3D VR movies using the OsiriX software equipped with the CMIV CTA plug‐in. Once created using the segmentation tool, the image series were exported in Quick Time Virtual Reality (QTVR) format and integrated within a web framework of the Educational Virtual Anatomy (EVA) program. A total of nine QTVR movies were produced encompassing most of the major arteries of the body. These movies were supplemented with associated information, color keys, and notes. The results indicate that, in general, students' attitudes towards the EVA‐program were positive when compared with anatomy textbooks, but results were not the same with dissections. Additionally, knowledge tests suggest a potentially beneficial effect on learning. Anat Sci Ed 2:61–68, 2009. © 2009 American Association of Anatomists.  相似文献

At the end of 2019, the Covid-19 pandemic spread caused restrictions in business and social spheres. Higher education was also severely affected: universities and medical schools moved online to distance learning and laboratory facilities closed. Questions arise about the long-term effects of this pandemic on anatomical education. In this systematic review, the authors investigated whether or not anatomical educators were able to deliver anatomical knowledge during this pandemic. They also discuss the challenges that anatomical education has faced over the last year. The search strategy was conducted between July 2020 and July 2021. Two hundred and one records were identified, and a total of 79 studies were finally included. How best to deliver anatomy to students remains a moot point. In the last years, the advent of new technologies has raised the question of the possible overcoming of dissection as the main instrument in anatomical education. The Covid-19 pandemic further sharpened the debate. Remote learning enhanced the use of technologies other than cadaveric dissection to teach anatomy. Moreover, from the analyzed records it appears that both from students' perspective as well as teachers' there is a clear tear between those who endorse dissection and those who believe it could be easily overcome or at least integrated by virtual reality and online learning. The authors strongly believe that the best anatomy teaching practice requires the careful adaptation of resources and methods. Nevertheless, they support cadaveric dissection and hope that it will not be replaced entirely as a result of this pandemic.  相似文献

Transforming clinical imaging data for virtual reality learning objects   总被引：1，自引：0，他引：1  
Advances in anatomical informatics, three‐dimensional (3D) modeling, and virtual reality (VR) methods have made computer‐based structural visualization a practical tool for education. In this article, the authors describe streamlined methods for producing VR “learning objects,” standardized interactive software modules for anatomical sciences education, from newer high‐resolution clinical imaging systems data. The key program is OsiriX, a free radiological image processing workstation software capable of directly reformatting and rendering volumetric 3D images. The transformed image arrays are then directly loaded into a commercial VR program to produce a variety of learning objects. Multiple types or “dimensions” of anatomical information can be embedded in these objects to provide different kinds of functions, including interactive atlases, examination questions, and complex, multistructure presentations. The use of clinical imaging data and workstation software speeds up the production of VR simulations, compared with reconstruction‐based modeling from segmented cadaver cross‐sections, while providing useful examples of normal structural variation and pathological anatomy.

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 underwent a self-directed learning session using either Anatomage, Magic Mirror, or traditional radiology atlases. A pre- and posttest 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 posttest 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.  相似文献

Thiel‐embalmed cadavers, which have been adopted for use in anatomy teaching in relatively few universities, show greater flexibility and color retention compared to formalin‐embalmed cadavers, properties which might be considered advantageous for anatomy teaching. This study aimed to investigate student attitudes toward the dissection experience with Thiel‐ compared to formalin/ethanol‐embalmed cadavers. It also aimed to determine if one embalming method is more advantageous in terms of learning functional anatomy through the comparison of student anterior forearm functional anatomy knowledge. Student opinions and functional anatomy knowledge were obtained through use of a questionnaire from students at two medical schools, one using Thiel‐, and one using more traditional formalin/ethanol‐embalmed cadavers. Both the Thiel group and the formalin group of students were surveyed shortly after completing an anterior forearm dissection session. Significant differences (P‐values <0.01) in some attitudes were found toward the dissection experience between cohorts using Thiel‐ vs. formalin‐embalmed cadavers. The Thiel group of students felt more confident about recognizing anatomy in the living individual, found it easier to identify and dissect anatomical structures, and indicated more active exploration of functional anatomy due to the retained flexibility of the cadaver. However, on testing, no significant difference in functional anatomy knowledge was found between the two cohorts. Overall, although Thiel embalming may provide an advantageous learning experience in some investigated areas, more research needs to be carried out, especially to establish whether student perception is based on reality, at least in terms of structure identification.

As human cadavers are widely used in basic sciences, medical education, and other training and research venues, there is a real need for experts trained in anatomy and dissection. This article describes a program that gives individuals interested in clinical and basic sciences practical experience working with cadavers. Participants are selected through an open application process and attend sessions focused on anatomical terminology, gross anatomy and radiography, and some of the educational applications of human cadavers. Dissection skills are honed during an intensive, two‐day cadaver dissection and orthopedic workshop. Participants communicate the knowledge they gain through table‐side discussions, reflect upon the experience during a memorial service, and submit written program evaluations. Additionally, the dissection and preparation of cadaveric materials accomplished in this course are used in the medical school gross anatomy course during the next academic year. From 2004 through 2008, the annual number of applicants increased from 40 to 167, and the number of participants increased from 25 to 43 per year. Program participants have represented diverse ethnic, educational, and professional backgrounds. Feedback from participants has been remarkably positive, including comments on the large amount of learning that takes place during the sessions, the positive impact the program has had on career choice, and the desire for program expansion. This program, which could be replicated at other institutions, teaches anatomy, prepares cadaveric prosections for teaching and training others, and encourages participants to pursue careers in anatomical and biomedical sciences.

We investigated the learning outcome of teaching an agent via immersive virtual reality (IVR) in two experiments. In Experiment 1, we compared IVR to a less immersive desktop setting and a control condition (writing a summary). Learning outcomes of participants who had explained the topic to an agent via IVR were better. However, this was only the case for participants who scored high on absorption tendency. In Experiment 2, we investigated whether including social cues in the task instructions enhances learning in participants explaining a topic to an agent. Instruction manipulation affected learning as a function of absorption tendency: Low-absorption participants benefitted most from being instructed to imagine they were helping a student peer pass an upcoming test, while high-absorption participants benefitted more when they were to explain the text to a virtual agent. The findings highlight the crucial role of personality traits in learning by teaching in IVR.  相似文献

Anatomy teaching methods have evolved as the medical undergraduate curriculum has modernized. Traditional teaching methods of dissection, prosection, tutorials and lectures are now supplemented by anatomical models and e‐learning. Despite these changes, the preferences of medical students and anatomy faculty towards both traditional and contemporary teaching methods and tools are largely unknown. This study quantified medical student and anatomy faculty opinion on various aspects of anatomical teaching at the Department of Anatomy, University of Bristol, UK. A questionnaire was used to explore the perceived effectiveness of different anatomical teaching methods and tools among anatomy faculty (AF) and medical students in year one (Y1) and year two (Y2). A total of 370 preclinical medical students entered the study (76% response rate). Responses were quantified and intergroup comparisons were made. All students and AF were strongly in favor of access to cadaveric specimens and supported traditional methods of small‐group teaching with medically qualified demonstrators. Other teaching methods, including e‐learning, anatomical models and surgical videos, were considered useful educational tools. In several areas there was disharmony between the opinions of AF and medical students. This study emphasizes the importance of collecting student preferences to optimize teaching methods used in the undergraduate anatomy curriculum.
