大型医疗影像设备运行可靠性自动评估技术

摘要
传统IDM可靠性评估方法不能根据医疗影像设备的运行状态估计基本停运概率,造成设备故障运行状态的产生。为解决上述问题,提出ARMA大型医疗影像设备运行的可靠性自动评估方法。在运行信度网络中,利用设备运行指标确定设备运行偏差,完成大型医疗影响设备运行的非精准性条件估计。在此基础上,利用非精准条件的贯蒙特卡洛仿真结果确定ARMA征兆属性、完善自动评估流程,实现大型医疗影像设备运行可靠性的自动评估。模拟对比实验结果显示,与IDM方法相比应用ARMA可靠性自动评估方法后,医疗影像设备停运概率降低40%,故障运行问题得到有效解决。
The traditional IDM reliability evaluation method can not estimate the basic outage probability according to the operation state of medical imaging equipment,which results in the failure operation state of equipment.To solve the above problems,an automatic reliability assessment method for ARMA large-scale medical imaging equipment is proposed.In the operation reliability network,the equipment operation deviation is determined by the equipment operation index,and the non-precision condition estimation of the large-scale medical equipment is completed.On this basis,the ARMA symptom attributes are determined and the automatic evaluation process is improved by using the non-accurate Monte Carlo simulation results,so as to realize the automatic evaluation of the operation reliability of large-scale medical imaging equipment.The simulation results show that compared with IDM method,the outage probability of medical imaging equipment is reduced by 40% and the problem of malfunction operation is effectively solved.
