Abstract:
Objective To explore the effect of quality control circle (QCC) in reducing the radiation dose during chest CT scan. Methods QCC was founded, activity themes were selected, activity schedule was planned, the reasons of high radiation dose was analyzed, countermeasures were planned and implemented jointly by circle members, and then per capita radiation dose and image quality before and after improving was compared to confirm the effect of QCC activities. The subjects of chest CT scan before and after improvement in our center were selected, included totally 218 cases, their average age was (47.05 ± 8.58) years, 162 were male, 56 were female, 44 cases had CT scan before improvement, 174 cases after improvement, and the data were analyzed by T-test and Chi-square test. Results The radiation dose per capita has declined from 13.75 mGy to 3.45 mGy, The rate of standard was 102.08%, progress rate was 74.91%. The rate of high-quality image was 92.52%. Compared with per capita radiation dose before and after the activities, the differences were statistically significant(P<0.001). The rate of high-quality image was 93.18% before activities, the percentage remained steady at 92.52% after the activities, there was no statistically significant differences in image quality(P>0.05). Conclusions Application of QCC not only reduced the radiation dose of the client without image quality changes, but also improved thinking and learning capacity, cooperative consciousness of the circle members.
