虚拟现实技术在计算机模拟病例系统中的应用

Utilization of virtual reality technology in computer-based case simulation system

背景:虚拟现实技术在医学领域的应用研究已经取得了丰硕的成果,展现出了很好的应用前景,是医学数字化研究的重要工具。目的:介绍基于虚拟现实技术的计算机模拟病历系统的应用与设计。方法:应用计算机检索CNKI数据库、维普数据库、万方数据库和EBSCO数据库,以"虚拟现实,模拟病例"为中文检索词,"casesimulations,CCS,virtual reality"为英文检索词,检索了1991/2011国内外相关研究文献85篇,最终纳入符合标准的文献20篇。结果与结论:虚拟现实技术在医学领域中的应用越加广泛,利用虚拟现实技术设计实现的模拟病历系统为医学工作者提供了新的互动式技能培训方式。实现了由计算机软件人机交互地对患者疾病状况的模拟,较逼真地模拟医生看病的临床过程。实现了对使用者的基本检查能力、高新诊断技术运用判断能力、检查结果判断能力、诊断能力、药物治疗能力、非药物治疗手段运用能力、综合治疗能力等实践技能的测评。模拟病历系统虚拟平台在医学教学发展和临床技能培训等方面有着良好的应用前景。

BACKGROUND： Virtual reality technology applied research in the field of medicine has achieved fruitful results and shows a good prospect, it is an important tool of digital medical research. OBJECTIVE： To introduce the design and application of computer-based case simulation system with virtual reality technology. METHODS： A computer-based search was performed on CNKI database, VIP database, Wanfang database and EBSCO database for the relate articles from 1991 to 2011 with the key words of ＂case simulations, CCS, virtual reality＂ in English and ＂virtual reality, case simulation＂ in Chinese. A total of 85 articles were obtained and finally 20 articles were included according to the inclusion criteria. RESULTS AND CONCLUSION： The application of virtual reality technology in the medical field has become more and more wide. The case simulation system designed by virtual reality technology provides the medical workers a new interactive skill training methods. The simulation of the patient＇s disease status by the interactive computer software is realized, and the clinical course is simulated realistically. And the assessment of the practical skills for the users were achieved, including basic inspection capacity, use and judgment of the high-tech diagnostic techniques, judgment of check results, diagnostic capability, drug treatment capacity, ability to use non-drug treatment and the comprehensive treatment capacity. The virtual simulation system platform has a good prospect in medical education and clinical skills training.
