Image quality and doses on selected studies of conventional radiology in designed hospitals

The medical exposures have a significant contribution to the doses received by the population, although it has been given minor attention than to other exposure forms, despite of existing potentialities of reducing doses to the patients as consequence of these applications. In the last years the scientific community and international organizations have defined requirements to contribute to that the doses to the patients are the minimum ones necessary to achieve their diagnostic objective. The present work gives the results obtained in the evaluation of the image quality and doses for exams of thorax PA, lumbar spine AP and lumbar spine lateral, carried out in 2 university hospitals of Havana, as well as the contribution on this investigation to the establishment of the guidance levels in the country. During the investigation it took as reference for the reference for the evaluation of the image quality of the radiological studies the emitted criteria by European Union. The behavior of these approaches for the case of the thorax studies presented its biggest difficulties with the achievement of the approaches related with the visualization of breathing structures, being the execution percentages lower than the remaining countries of the region. In general the behaviour of the approaches of quality image in the ARCAL project. The behaviour of the image quality approaches are associated to different technical factors. The obtained results of doses for thorax PA are bigger than the recommended International Standards Basics in both hospitals. (author)
