Objective： To analyze the factors affecting operation rate of TomoTherapy system, which had higher failure rate compared to the traditional accelerator. Relevant countermeasures had been proposed to increase the operation rate. Methods：To discuss the main factors affecting operation rate of TomoTherapy, the failure record had been analyzed. Results： Temperature cooling system, compressed air system, deteriorating parts and database system had been summarized to be the main factors caused the failure of the TomoTherapy. Conclusion：Some corresponding maintenance measures specific to the four factors had been proposed in order to reduce TomoTherapy failure rate and increase TomoTherapy service efficiency.
