Abstract：Objective To discuss the importance of QM (Quality Management) and the QC (Quality Control) testing methodology for CT (Computed Tomography) scanners so as to formulate appropriate QA regulations and QC testing procedures for the department. Methods The QA regulations of CT scanners were optimized in the department according to practical work experience. Additionally, with deployment of the self-designed simple methodologies, QC testing of CT scanners was carried out on a regular basis from multiple aspects including the average CT value of water phantoms, uniformity of CT values, the level of noise, high-contrast and low-contrast resolutions as well as the accuracy of distance, volume and angle measurement. Results The QC testing methodologies of CT scanners have proven its effectiveness and feasibility, which ensured the best performance of CT scanners and optimized CT examinations.Conclusion QM of CT scanners is complex but of great importance. It is suggested to design an easy and simple testing methodology according to the practical conditions in the department. And performance testing of CT scanners should be performed on a regular basis in order to ensure the safety of medical examinations.
