Although radiographic exposures are individually low dose, in 2016 there were 275 million in the U.S.; the broad population makes consistent dose and image quality important. A large institution faces significant challenges to achieving this: vast data collec...

Iterative and deep learning image reconstruction (IR and DLIR) are valuable for reducing dose in modern CT but have the effect of reducing lesion edge sharpness. If sharpness loss becomes contrast dependent at some threshold, the decrease in sharpness may exc...
