Abstract：Magnetic resonance imaging (MRI) equipment has been widely used in clinical medicine. Long-term use of full load
leads to a gradual increase in the incidence of MRI equipment faults, which puts forward higher requirements for clinical engineers
to quickly remove faults and ensure the normal operation of equipment. In this paper, two artifact repair cases of GE Signa Excite 1.5 T
MAGNETIC resonance imaging system and one non-responsive repair case of transceiver and processing subsystem (TPS) were
listed. Respectively for GHOST artifact, white noise artifact and TPS NOT RESPONDING error, used a variety of test methods,
segmentation and elimination, replacement components to repair the fault, gradually analyzed the cause of the fault, respectively
by replacing the gradient control board, reinstalling the connection line adapter and replacing the RRF/DIF board to restore normal
operation of the equipment. This paper aims to communicate and learn from the majority of clinical engineers, and jointly improve
the equipment support capability.
