GE Discovery MR750 Maintenance of Magnetic Resonance Imaging System Faults
Magnetic resonance imaging system is a medical examination equipment that utilizes the phenomenon of hydrogen atom nuclear magnetic resonance imaging in the human body.Compared with CT and DR imaging techniques,magnetic resonance imaging has no ionizing radiation hazards and can be used for multi-directional tomography.The image contrast information is rich and diverse,which is conducive to disease diagnosis.It is widely used in cutting-edge medical imaging diagnosis.The GE Discovery MR750 is one of the main models of the General Electric Medical Systems Group,mainly composed of the main magnet system,RF system,gradient system,computer and image reconstruction system.Its structure is complex,the system is large,and there are many corresponding faults.This article analyzes and summarizes common faults in RF systems,gradient systems,computers,and image reconstruction systems.In three cases of faults,error information and phenomena are analyzed,and combined with maintenance experience,the faults are ultimately resolved.
