Abstract: Mastering the structure,composition and working principle of digital subtraction angiography(DSA)equipment is an important prerequisite for medical engineers to carry out daily maintenance and repair management.By analyzing the structural composition and functional components of DSA from the aspects of X-ray source,mechanical drive,host control and image output,the working process of subtraction imaging was described according to Beer-Lambert law,and the influencing factors of DSA image quality were summarized.At the same time,taking the Allura XPer FD20 DSA equipment as an example,the failure cases of examination bed,rack and temperature control that occurred in clinical use were analyzed,and the fault investigation and processing were carried out from the hardware structure and circuit module of the equipment,and the equipment fault alarm information was solved in time to ensure the operation quality of the equipment and improve the efficiency of fault maintenance.
