Automatic exposure control in the head of a pediatric patient. Automatic exposure control in the head of a pediatric patient. The quality reference tube current–time product for this study is equal to 220 mAs, corresponding to a CTDIvol equal to 34 mGy. However, because automatic exposure control was used, the mean effective tube current–time product was 90 mAs, corresponding to a CTDIvol of 13.77 mGy. J.C. Montoya et al.
