Modification of chest radiography exposure parameters using a neonatal chest phantom.

Background: The acquisition of chest radiographs in neonates is of critical importance in diagnostics because of the risk of respiratory distress syndrome and pneumothorax in preterm infants.

Objective: To achieve a dose reduction while preserving a diagnostic image quality for chest radiographs of neonates.

Materials And Methods: All radiographs, generated on a fully digital X-ray unit by using a neonatal chest phantom, were evaluated under variation of the tube voltage (40-70 kV) and mAs levels (1-10.
