Abstract:
Objective To investigate the current status of quality control of radiological diagnosis and treatment equipment in Shenzhen City, explore the problems in quality control testing of radiological diagnosis and treatment equipment, and provide control strategies. Methods According to the requirements of the Special Monitoring Work Plan for Radiation Health in Shenzhen, quality control tests were carried out on some radiological diagnosis and treatment equipment in Shenzhen according to the test items and methods of the currently valid national standards. Results From 2019 to 2023, a total of 72 medical institutions participated in radiological health monitoring program in Shenzhen, and 839 quality control tests were performed on radiological diagnosis and treatment equipment. The qualified rate was 91.8% in preliminary tests. The qualified rates of radiological diagnosis, radiotherapy, and nuclear medicine equipment were 91.9%, 96.3%, and 62.5%, respectively. The primary unqualified items were response uniformity, flatness of the X-ray irradiation field, and intrinsic spatial linearity. Conclusion The qualified rate in quality control of nuclear medical equipment is relatively low. Medical institutions should strengthen the routine maintenance of radiological diagnosis and treatment equipment. Radiological health technical service institutions should enhance the training of technical personnel to ensure the health and safety of patients and radiation workers.
