Objective： In radiation therapy, the accelerator will be stopped and interrupted treatment as soon as dose interlock appeared. And the linear accelerator dose interlock is multiple one in all kinds of the accelerator interlock faults. To study and explore general maintenance skills is in favor of quick analysis, and making the accelerator recovered in time, so as to ensure the normal treatment of the patients timely according to established plan. Methods： The author briefly analyzed the dose interlock and its factors, gave advice general maintenance skills and the general solving path of dose interlock, based on the dose interlock examples of SIEMENS ONCOR linear accelerator. Results： Using the general solving path, connecting with the practice, it can deal with most dose interlock troubleshooting and ensure the clinicalradiation therapy. Conclusion： It has been found that the method to deal with these dose interlock is reliable an~ effective. It can help improve the maintenance speed and skill of dose interlock for engineers and technicians.
