To shield or not to shield: shielding may have unintended effects on patient dose in CT
European Radiology, 2023 Abstract Objectives The aim of the patient out-of-plane shield is to reduce the patient radiation dose. Its effect on tube current modulation was evaluated with the out-of-plane shield visible in the localizer but absent in the scan range in chest CT with different CT scanners. Methods
