Today more than 20 million of routine chest examinations are performed in Ukraine annually [1]. More than 60 percent of them are make with the help of film fluorographs (Fig.1-2) the main disadvantages of which are low information content and high effective dose on the patient - 5 times higher comparing to chest radiography. According to the data received by Grigoriev Institute for Medical Radiology real effective doses on the patients examined with fluorographs, which reached the end of their service life exceed 1.0 mSv,...

Ukraine has such experience. It is through this process that within 2000 – 2006 substitution of 30% of fluorography with preventive digital radiography became possible (Fig.4-5). Today there are additional modernization options which make it possible not only to substitute fluorography with digital radiography, but to exclude carrying out of fluoroscopy without X-ray II. Today Ukraine produces both digital receptors (DR) for radiography and dynamic DR for radiography, fluoroscopy and X-ray tomosynthesis (Fig.6-7) If ca. $50,000 is required to purchase a new digital fluorograph, ca....

The transfer of analogous X-ray apparatuses to digital technology of X-ray imaging by means of modernization of the working X-ray equipment using new X-ray technologies is the most effective way to improve the radiation safety of X-ray diagnostics in Ukraine.
