Quality control analysis and application of CT equipment / 中国医学装备

ABSTRACT

Objective:We propose a quality control plan which is suitable for the actual situation of our hospital and keep our CT equipment in a normal working condition, so that we can get the best image quality.Methods: According to “GB 17589-2011 Specification for quality assurance testing of X-ray computed tomography apparatus”, we can get quality testing data of GE Lightspeed VCT from different time.Results: The indicators in quarterly testing meet the requirements, and have little difference with ideal value. Meanwhile the testing indicators have no significant change after calibration. The indicators in half year testing meet the requirements, and have large difference with ideal value. Meanwhile the testing indicators have significant change after calibration. Conclusion: According to the test results, combined with the daily use of experience, we carry out the quality control program for the actual situation of our hospital. It reduces the failure rate of the equipment, and improves the picture quality of CT equipment.
