Cover Story: Automatic exposure control (AEC) is widely used to achieve appropriate radiation dose modulation in CT according to the degree of attenuation by the patient. AEC determines radiation dose mainly based on the scout images, and off-centering of the patient affects the dose due to improper magnification. The new version of CARE Dose 4D, Siemens AEC software, modulates radiation dose primarily with the posteroanterior (PA) scout image and uses the lateral (Lat) scout image for off-center correction when both are available. This phantom study demonstrated successful off-center correction using the new version. Moreover, although scout imaging parameters influenced dose modulation with the PA and Lat scout images using the previous version, such influences were not observed using the new version, enabling a reduction in scout radiation dose. View this paper
