Abstract：Objective To establish a set of performance state detection method of digital subtraction angiography (DSA) system
to provide performance data basis for the full life cycle management of DSA. Methods DSA performance module was used for
quality evaluation. The performance parameters included tube voltage deviation, spatial resolution, air kerma rate, minimum size of
simulated vessels, and contrast linearity. Results The performance parameters of DSA were collected and analyzed, and the detection
results of four DSA were all qualified. Conclusion By establishing the DSA image quality evaluation system, the medical equipment
management department can carry out daily quality control and preventive maintenance on the application quality of DSA, ensuring
that the clinical use department can obtain reliable image quality in the full life cycle of DSA.
