Information × Registration Number 0213U000123, 0111U010160 , R & D reports Title Quality assurance of diagnostic imaging and optimisation of patients exposure on the basis of established national diagnostic reference levels for radiodiagnostic examinations. popup.stage_title Head Pylypenko M.I., Registration Date 17-01-2013 Organization Grigor'ev Institut for Medical Radiology popup.description2 Object of the research: methodological base of Ukraine and EU countries concerning radiation protection of patients at radiodiagnostic investigations, methods of quality assurance of radiographic investigations, irradiation doses of the patients at radiodiagnostic investigations. Purpose of the work: to work out a program of quality control of radiological imaging with optimization of the patients exposure based on the established diagnostic reference levels (DRL) for improvement of the efficacy of radiodiagnostic investigations and reduction of the risks of stochastic effects. Methods of research and equipment: dosimetry (ionization and thermoluminescent), a method of expert assessment, methods of mathematical statistics; thermoluminescent unit PCL-3, dosimetry kit TRIAD model 10100А, digital x-ray dosimeter ДРЦ-01, universal test-object for control of geometry of diagnostic image ТУР-01. Theoretical and practical results: Methodological approaches to the control of radiogrsam quality using test-objects were studied. Control of dose-forming parameters of 8 x-ray diagnostic units of 3 hospitals of Kharkiv was done. Testing the methods of geometry control of diagnostic image and method of expert assessment of x-ray image quality was started. 256 measurements of entrance surface doses of the patients for 3 radiography examinations on 6 x-ray diagnostic units of Kharkiv were done. Phantom measurement was used in 19 calculations of effective doses for three types of x-ray diagnostic procedures of 9 diagnostic units. Novelty: for the first time, the information about the methodology of control and assessment of the quality of x-ray images and optimization of dose load to the patients at x-ray investigations was systematized.. Area of application: radiation hygiene, medicine, x-ray diagnosis. Product Description popup.authors Масіч О.В. Павліченко Ю.В. Пилипенко М.І. Стадник Л.Л.
