Transition from Screen-Film to Digital Radiography: Evolution of Patient Radiation Doses at Projection Radiography

Purpose: To retrospectively evaluate patient radiation doses in projection radiography after the transition to computed radiography (CR) in the authors' hospital. Materials and Methods: The hospital's ethical committee approved the study and waived informed consent. In 2001, a dose reduction initiative was implemented, which involved collecting radiographic parameters, calculating patient entrance doses, and monitoring changes with an online...
