摘　　要：目的 由于超声诊断仪故障类型复杂多变,因其实时性使得获取准确故障数据困难较大,且仅通过人工诊断具有主观性,导致诊断效率不高。为了提高对超声诊断仪故障诊断的精准性,设计超声诊断仪无图像故障的快速诊断及应急维修方法。方法 利用实时监测环境监测超声诊断仪应用状态,计算超声诊断仪故障出现的时刻,获取故障数据,并对其进行初次特征提取;通过计算故障特征的权重值,进行二次特征提取,构建故障矩阵;利用故障诊断函数,诊断超声诊断仪故障;根据诊断结果,提出应急维修方案,完成超声诊断仪无图像故障的快速诊断及应急维修方法的设计。结果 在实验测试中,超声诊断仪无图像故障的快速诊断及应急维修方法诊断时间仅为0.89 ms,诊断效率更高。结论 通过设计快速诊断及应急维修方法,可以提高超声诊断仪的响应速度和诊断准确性,从而优化医疗服务质量,更好地为患者提供可靠的诊断结果。Objective Due to the complexity and variability of fault types in ultrasound diagnostic instruments,considering real-time performance,it is difficult to obtain accurate fault data,and it is subjective to only manually diagnose,resulting in low diagnostic efficiency.In order to improve the accuracy of fault diagnosis for ultrasound diagnostic equipment,to design a rapid diagnosis and emergency maintenance method for imageless faults in ultrasound diagnostic instruments.Methods The real-time monitoring environment was utilized to monitor the application status of ultrasound diagnostic instruments,the time of failure in ultrasound diagnostic instruments was calculated,the fault data was obtained,and their initial features were extracted.By calculating the weight value of fault features,their secondary features were extracted,and then the fault matrix was constructed.The fault diagnosis function was used to diagnose the faults of ultrasound diagnostic instruments.Then the corresponding emergency maintenance plans were proposed based on the diagnosis results,and the rapid diagnosis and emergency maintenance method for imageless faults in ultrasonic diagnostic instruments was completed.Results In the experimental testing,the diagnosis time of rapid diagnosis and emergency maintenance method for imageless faults in ultrasonic diagnostic instruments was only 0.89 ms,with higher diagnostic efficiency.Conclusion By designing rapid diagnosis and emergency maintenance method,the response speed and diagnostic accuracy of ultrasound diagnostic equipment can be improved,thereby optimizing the quality of medical services and providing reliable diagnostic results for patients.
