Abstract：Objective To evaluate the time stability of MRI systems and improve the reliability of clinical and research results. Methods Combined with the existing evaluation methods for assessment of MRI time stability, to discuss the application of SPM in evaluating time stability. Results Obtained the excursion information of each axis and roller, and analyzed the effects of the excursion on the time stability of MRI systems. Conclusion The result of the study shows the time stability of the system in detail, including translation and rotation, which can be used to guide the clinical and scientific research.
