医用核磁共振成像系统的风险故障分析及维护保养

Risk and malfunction analysis and maintenance of magnetic resonance imaging system

目前,医用核磁共振成像系统与临床诊断密切相关,在疾病诊断中发挥了非常重要的作用。核磁共振成像设备制动化程度高,结构精密,所以在运行中存在潜在的风险,且易出现故障。因此,本文通过从核磁共振成像系统原理和运行程序方面分析存在的潜在风险,从电气系统、运行方面及图像方面分析常见故障,进而总结核磁共振成像设备的维护和保养方法,使操作人员熟知医用核磁共振成像系统的常见风险故障,为操作人员提供排除故障和日常维护作参考,提高临床诊断效率。

Currently, the medical magnetic resonance imaging system（MRI） system is closely related to the clinical diagnosis and it plays a very important role in the diagnosis of diseases. MRI equipment has potential risks and easily has malfunction due to its high-degree automation and precise structures. Therefore, this paper analyzes potential risks from aspects of theories of MRI system and operating procedure and common malfunction from aspects of electrical system, operation and imaging to summarize maintenance methods of MRI equipment. Thus, it can make operation staff know well about common risk malfunctions and provide reference for remedying faults and daily maintenance to improve efficiency of clinical diagnosis.
