Abstract:
Objective To assess the technical levels of computed tomography (CT) quality control testing capabilities among radiological health technology service institutions in Hubei Province, China. Methods Ten radiological health technology service institutions in Hubei Province were organized to participate in an inter-institutional capability comparison of selected indicators in CT quality control testing with reference to the Specification for testing of quality control in X-ray computed tomography (WS 519—2019). The robust Z-score method was employed to evaluate the results of the capability comparison data from the ten institutions. Results Six institutions achieved a "satisfactory" rating in all assessed indicators, with a satisfaction rate of 60%. Indicators rated as "unsatisfactory" or "questionable" included "positioning light accuracy", "uniformity", "noise", and "high-contrast resolution". Conclusion The CT quality control testing capabilities of some radiological health technology service institutions in Hubei Province require further enhancement. Improved training and education for testing personnel are recommended.
