Modeling and simulation of an anatomy teaching system

Specimen observation and dissection have been regarded as the best approach to teach anatomy,but due to the severe lack of anatomical specimens in recent years,the quality of anatomy teaching has been seriously affected.In order to disseminate anatomical knowledge effectively under such circumstances,this study discusses three key factors(modeling,perception,and interaction)involved in constructing virtual anatomy teaching systems in detail.To ensure the authenticity,integrity,and accuracy of modeling,detailed three-dimensional(3D)digital anatomical models are constructed using multi-scale data,such as the Chinese Visible Human dataset,clinical imaging data,tissue sections,and other sources.The anatomical knowledge ontology is built according to the needs of the particular teaching purposes.Various kinds of anatomical knowledge and 3D digital anatomical models are organically combined to construct virtual anatomy teaching system by means of virtual reality equipment and technology.The perception of knowledge is realized by the Yi Chuang Digital Human Anatomy Teaching System that we have created.The virtual interaction mode,which is similar to actual anatomical specimen observation and dissection,can enhance the transmissibility of anatomical knowledge.This virtual anatomy teaching system captures the three key factors.It can provide realistic and reusable teaching resources,expand the new medical education model,and effectively improve the quality of anatomy teaching.

Opinions of Students on the Contribution of the DIVA 3D Virtual Dissection Table to the Teaching of Anatomy at the Faculty of Medicine and Odontostomatology of Bamako

Objective: Study the contribution of the DIVA 3D dissection table in the teaching of anatomy at the Faculty of Medicine and Odontology of Bamako. Material and Methods: This was a qualitative study carried out from November 1 to December 30, 2023 at the clinical and morphological anatomy laboratory of the Faculty of Medicine and Odontostomatology of Bamako. Included in this study were students who participated in practical and tutorial sessions. The variables studied during this study were: the previous performance of dissection on a cadaver by the students, the opinion of the students on dissection on a cadaver, the replacement of dissection on a cadaver by virtual dissection in the absence of a body, the level student satisfaction. Results: We surveyed 130 participants. The average age was 22 ± 0.2 years with extremes of 17 and 29 years. 95.3% of participants were students. According to 66.7% of participants, virtual dissection is a good palliative in the absence of a corpse. 95.3% of participants found using the virtual dissection table easy with an average of 7.88 ± 1.4. The overall assessment was well rated by 99.3% of participants. Conclusion: According to the results of this study, the virtual dissection table should be improved by integrating commented videos. The use of the DIVA 3D virtual dissection table during practical and tutorial sessions is well appreciated by the students. We believe that the teaching of anatomy using 3D digital technology should be included in the study programs of the Faculty of Medicine and Odontostomatology.

The Role of Anatomical Specimens in the Teaching of Anatomy

characteristics,complex content,and it is difficult to understand.In view of the nature of the subject,many different models and specimens are required during teaching,increasing the difficulty of its teaching.Although the mode of medical teaching is constantly updating,anatomical specimens are still important in the teaching of anatomy,as they help students to understand the organs,their positions,and structural forms as well as to better grasp the theoretical aspect.In addition,anatomical specimens and medical students contact condition can affect the teaching effect.Therefore,it is imperative to give full play to the role of anatomical specimens in anatomy teaching to improve the teaching effect.This paper summarizes the research on the use of anatomical specimens in the teaching of anatomy.

Development and application of digital assistive teaching system for anatomy

Background Anatomy is a required course for all medicine-related industries.In recent decades,the teaching quality and effect of anatomy have been compromised by factors including a decrease in human body specimens,dampened enthusiasm for the discipline,reduced teaching hours of anatomy,scale expansion of medical education,and obstacles in performing field autopsies and observations.Methods Based on China's digitalized visible human research achievements,this article extracts the boundary information of anatomic structures from tomographic images,constructs three dimensional(3D)digital anatomical models with authentic texture information,and develops an anatomy assistive teaching system for teachers and students based on the knowledge points of anatomy,to meet the anatomy teaching requirements of different majors at various levels.Results This scientific,complete,and holistic system has produced over 60003D digital anatomical models,5000 anatomy knowledge points,50 anatomical operation videos,and 150 micro demonstration classes,with teaching contents for different majors and levels,such as systematic anatomy,topographic anatomy,sectional anatomy,anatomy of motion,and virtual anatomical operation table.Ranging from network terminals,desktops,touchscreen 3D displays,desktops,and projection 3D volumetric displays to augmented reality,its diversified interactive forms meet the requirements for a learning environment in different settings.Conclusions With multiple teaching and learning links covered,such as teaching environment,teaching resources,instructional slides,autonomous learning,and learning effect evaluation,this novel teaching system serves as a vital component and a necessary resource in anatomy teaching and functions as an important supplement to traditional anatomy teaching.Applied and promoted in most medical colleges and schools in China,this system has been recognized and approved by anatomy teachers and students,and plays a positive role in guaranteeing the effect and quality of anatomy teaching.
