Purpose: optimization of radiation protection of patients on the base of development of comprehensive quality assurance program of X-ray examinations in Diagnostic Radiology. Methods and equipment: ionization and thermoluminescence dosimety, methods of mathematical statistics; thermoluminescence unit PCL-3, universal dosimeter Piranha 657, ionization dosimeter DRC-01, universal test object TUR-01 for image quality control, phantom FLURO for image quality control in radiography and fluroscopy, mammography phantom СIRS Theoretical and practical results: the information concerning the quality assurance programs and optimization of radiological examinations was systematized; the impact of technique conditions during X-Ray examinations on the image quality and the doses of adult patients for radiography, fluoroscopy and mammography were investigated. In according with developed protocols the main physical and technical parameters and the quality of images were studied for 32 radiography, 18 fluoroscopy and 11 mammography X-ray units in 18 medical hospitals. The patients' doses for 12 types of radiography: 1950 direct TLD-measurements and 5750 calculations on the base of information about examination's conditions from registration forms, 3 types of fluoroscopic examinations (580 measurements and calculations) and the average glandular doses on the breast from mammography examinations (470 measurements) were determinated. The national reference levels for 12 radiographic, 3 fluoroscopic and mammographic examinations were established. Novelty: firstly in Ukraine the quality control program in conventional diagnostic radiology was developed to unify of methods and conditions for testing of X-ray diagnostic equipment. The basic tests of control the technical parameters of X-ray machines, the image receivers and methods for dose assessment of patients with radiography, fluoroscopy and mammography were defined in QC program.Effectiveness of results implementation: implementation of quality control program in diagnostic radiology will allow to optimize of the X-ray examination and informativeness, to reduce the population medical exposure and the risk of radiation-induced tumors. Field of application: radiation hygiene, X-ray diagnostics. Product Description popup.authors Волошина Н.М. Дем'яненко В.В. Дригваль А.А. Кургузов Є.І. Носик О.В. Павліченко Ю.В. Пилипенко М.І.
