CT dose reduction using Automatic Exposure Control and iterative reconstruction: A chest paediatric phantoms study

Highlights • Automatic Exposure Control (AEC) reduces dose delivered in chest paediatric MDCT. • Application of AEC results in a deterioration of image quality indices. • Iterative reconstruction (IR) compensates for the deterioration of image quality indices. • IR changes the amplitude and the spat...

Description
Summary:Highlights • Automatic Exposure Control (AEC) reduces dose delivered in chest paediatric MDCT. • Application of AEC results in a deterioration of image quality indices. • Iterative reconstruction (IR) compensates for the deterioration of image quality indices. • IR changes the amplitude and the spatial frequency in Noise Power Spectrum curves. • AEC/IR reduce the dose by 43–91% while maintaining diagnostic image quality.
