摘　　要：磁共振成像主要原理是将人体放置在特殊磁场中,并利用无线电射频脉冲对人体内部氢原子核进行激发,使氢原子核共振吸收能量。在结束脉冲后,氢原子核能够按照相应频率发出信号,使人体内部形态被磁共振设备接受,经计算机处理随后获得图像。西门子1.5T磁共振属于医院内部最为重要的医疗设备,可以对患者全身每个部位进行深度扫描,从而发现病灶。作为高端MRI产品,西门子1.5T磁共振图像更为清晰,且成像速度较快,扫描范围较大同时扫描声音较低,降低对患者诊疗过程中的影响,可以进一步缩短诊断时间,为患者后续治疗奠定基础。西门子1.5T磁共振水冷系统作为该设备重要组成部分,直接影响到西门子1.5T磁共振的实际运行状态。本次研究针对西门子1.5T磁共振水冷系统的工作原理及故障维修展开分析。The main principle of magnetic resonance imaging is to place the human body in a special magnetic field,and use radio frequency pulses to excite the hydrogen nuclei inside the human body,so that the hydrogen nuclei absorb energy by resonance.After the end of the pulse,the hydrogen nuclei can send out signals according to the corresponding frequency,so that the internal shape of the human body is accepted by the magnetic resonance equipment,and the image is obtained after computer processing.Siemens 1.5T MRI is the most important medical equipment in the hospital.It can deeply scan every part of the patient’s body to find the lesions.As a high-end MRI product,Siemens 1.5T magnetic resonance imaging has clearer images,faster imaging speed,larger scanning range,and lower scanning sound,reducing the impact on the patient's diagnosis and treatment process.This can further shorten the diagnosis time and lay the foundation for subsequent treatment of patients.As an important part of the equipment,Siemens 1.5T magnetic resonance water cooling system directly affects the actual operation state of Siemens 1.5T magnetic resonance.This research analyzes the working principle and fault maintenance of Siemens 1.5T magnetic resonance water cooling system.
