Abstract：Objective This paper mainly introduced the application principle of CAN communication in Siemens CT Definition AS, the common failures of CAN communication and troubleshooting methods. Methods Taking the Siemens CT Definition AS in our hospital as the research object, 2 cases of CAN communication failures in actual application were analyzed, the causes of the failure were found, and the corresponding solutions were formulated according to the results of the analysis. Results Through the analysis of CAN communication failure phenomenon and equipment error information, the fault could be eliminated, which provided reference for the maintenance of the equipment. Conclusion Understanding and mastering the principle of CAN communication in large medical devices is of great significance to the use and maintenance of equipment.
