Abstract: In recent years, with the wide application of magnetic resonance imaging (MRI) equipment in clinical practice, the quality of the equipment causes adverse events, which put pressure on manufacturers, at the same time, it puts forward higher requirements for medical device supervisors. In order to help the medical device supervisors to clarify the key points of verification, this paper analyzes the main risk points in the production process of the product according to the medical device good manufacturing practice(GMP), and puts forward the suggestions for field verification, which has practical significance for the submission of verification efficiency.
