Abstract：The mobile C-arm X-ray machine has the advantages of small size, high flexibility, real-time imaging, etc. It has found an increasingly wide utilization in clinical operations, and its number of configurations in medical institutions is increasing year by year. In order to ensure that the image quality of mobile C-arm during operation meets the diagnostic requirements and the radiation output dose meets the national standard, it is necessary to carry out metrological verification. This paper proposes a verification method based on the traceable measuring instruments. The verification items include the air kerma rate of radiation output, half-value layer, spatial resolution, low-contrast resolution and X-ray tube voltage and so on, which provide technical support for the supervision and management of regulatory authorities and user quality control.
