Abstract
An apparatus for performing automatic exposure control in a computed tomography (CT) imaging system including an X-ray source is provided. The apparatus includes processing circuitry configured to acquire helical scan data from a scout scan performed on a first imaging object, determine a target noise standard deviation (STD) for an imaging scan to be performed on the first imaging object after the scout scan, retrieve a pre-stored attenuation-noise-dose relationship relating attenuation of X-rays from the X-ray source that pass through a second imaging object, noise present in reconstructed i…
