Objective To analyze the status of CT quality control in some hospitals in Guiyang,and provide the basis for fur-ther strengthening the quality control management of medical CT. Methods According to the national standard (GB17589-2011),to carry on quality control testing for 24 sets of CT in some hospitals in Guiyang,and analyze the results of testing. Results The passing rate of the first testing was 87.5%, the passing rate of CTDIw (head) of which was 91.7%,the passing rate of the value of CT (water), noise, low contrast detection ability was 87.5%,the passing rate of reconstruction thickness deviation, uniformity, linear of CT value was 95.8%, the passing rate of the other parameters was 100%. Through on-site commissioning by engineer,the passing rate of CT testing reached 100%. Conclusion Regular quality control testing for CT in hospital, can effectively guarantee the safe operation of CT,and reduce the patient dose as much as possible while obtain-ing the sufficient diagnostic information.
