目的 本研究旨在利用知识图谱分析CT机维护领域的研究现状与热点,通过多维度的数据统计揭示主要研究方向和趋势.方法 本文采用Citespace和Vosviewer软件,对CT机维护现状进行年度发文量、学科发文量和关键词聚类等方面进行可视化分析.结果 对筛选出的 396 份CT机维护领域的文献进行可视化分析.年度发文量分析显示,2019 年为高峰期,随后发文量呈现下降趋势,反映出近年来研究的关注度有所波动.关键词聚类分析揭示了 6 个主要聚类,涵盖了从维修管理到故障分析和设备维护的广泛主题.关键词频次分析显示,维修、故障、保养等词汇频率较高.关键词中心相关性分析显示,"故障维修"以最高的中心相关性位居榜首,其他关键词如CT设备、准直器和保养等也显示出在设备性能优化和故障预防方面的重要性.结论 基于Citespace和Vosviewer软件对CT机维护领域研究现状进行分析,全面揭示了CT机维护领域的研究动态和趋势,为未来研究方向的制定提供了深刻洞察和理论支持.
Analysis of CT machine maintenance status based on Citespace and Vosviewer
Objective This study aims to use knowledge graph to analyze the research status and hot spots in the field of CT machine maintenance,and reveal the main research direction and trend through multidimensional data statistics.Methods In this paper,Citespace and Vosviewer software were used to visually analyze the current status of CT machine maintenance in terms of the annual publication amount,subject publication amount and keyword clustering.Results 396 selected literatures in the field of CT machine maintenance were visually analyzed.Analysis of the annual number of published papers shows that 2019 was the peak,and then the number of published papers showed a downward trend,reflecting the fluctuation of research attention in recent years.The analysis of the number of disciplinary papers shows that biomedical engineering,medical and health policies and laws and regulations,and instrumentation industry are the leading disciplines.Keyword cluster analysis reveals 6 main clusters covering a wide range of topics from maintenance management to fault analysis and equipment maintenance.Keyword frequency analysis shows that the frequency of words such as repair,fault and maintenance is higher.Keyword center correlation analysis shows that"fault repair"tops the list with the highest central correlation,and other keywords such as CT equipment,collimator and maintenance also show the importance of equipment performance optimization and fault prevention.Conclusion Based on Citespace and Vosviewer software,the current research status in the field of CT machine maintenance was analyzed,which fully revealed the research trends and trends in the field of CT machine maintenance,and provided profound insight and theoretical support for the development of future research directions.
