Approach to CT dose optimization: Role of registries and benchmarking

Abstract

Past two decades have seen remarkable improvements in both hardware and software technologies related to computed tomography (CT) (Tabari et al. 2017). Starting from the addition of multiple detector rows to the single-detector-row helical CT scanners in the late 1990s to the ensuing embellishment with powerful X-ray tubes and efficient detectors, CT has come a long way. These technological advances helped multidetector row CT scanners cement an indispensable role in patient care but also led to concerns over associated radiation doses.
