摘　　要：目的分析飞利浦大孔径CT六年运行故障原因,找出共性问题,制定相应保养方案并对未来几年故障发生率进行模拟预测。方法收集2012-2018年间大孔径CT故障数据,使用SPASS 19.0软件中曲线估计功能分析故障发生次数与时间的关系,并做出预测;使用帕累托图分析功能分析故障类型。结果6年共发生故障28次,其中刚使用半年内,故障发生率最高(5次),随后趋于平稳。经曲线估计得到线性函数模型为y=-0.033x+2.099(R2=0.003),未来3年内每半年发生故障次数约2次。帕累托图显示发生数据采集故障16次,其中治疗床和供电电源系统故障分别为3次,占比达71%,是主要故障来源。结论大孔径CT故障统计分析有助于科室维修人员更好了解CT,制定有效保养方案,减少故障发生,并对未来故障发生率有个预判。Objective To analyze the 6-year operation faults of PHILIPS Brilliance big bore CT,identify the common problems,make corresponding maintenance plans,reduce the incidence of failures,and carry out simulation prediction of the occurrence rate of failures in the next few years.Methods The failure data of Brilliance big bore CT from June 2012 to June 2018 were collected,and the curve estimation function in SPASS 19.0 software and the pareto diagram were used to analyze the relationship between the number of failures,time and failure types,and the prediction was made.Results A total of 28 faults occurred during the 6-year opeation of Brilliance big bore CT.During the first half year,five times of faults occurred with the highest fault rate and then tended to stabilize.The linear function model was obtained using the curve estimation:y=-0.033x+2.099(y for the number of fault,unit for times,x for the unit of time for half a year),the model of R2=0.003.In the next three years,approximately twice faults occurred within half year.The pareto chart showed that 16 faults occurred during data collection,including 3 faults in the treatment bed and 3 faults in the power supply system,respectively.The accumulative ratio of the above three faults was 71.4%,which were the main fault sources.Conclusion The fault statistical analysis of Brilliance big bore CT is helpful for department maintenance personnel to better understand CT,develop effective maintenance programs,reduce the occurrence of faults,and predict the incidence of faults in the future.
