Improvement of Contrast in Digital X-ray Images Considering Exposure Dose for Stout Patients Undergoing Fluorography Chest Screening

Due to high level of tuberculosis in Ukraine, the fluorography chest screening is the most frequent diagnostic procedure which is performed annually for adult population and contributes to collective effective dose. During the diagnostic examination, the people with high body mass index obtain higher exposure dose, compared to average patients. The higher exposure dose is required for receiving diagnostic X-ray images with sufficient visual quality parameters. In present study, the approach in reduce of exposure dose for patients with high body mass index was explored in close to clinical fluorography examination conditions with application of contrast improvement methods
