Fig. 3 — DLP-normalized effective dose to diameter. a Plot shows exponential fit of DLP-normalized effective dose to abdominopelvic diameter with comparison to k coefficients from Shrimpton et al. [15] for trunk examinations (Shrimpton data presented as +) of reference pediatric patients developed by Cristy and Eckerman [37] at age 0, 1 year, 5 years and 10 years. The average abdominopelvic diameters of the reference phantoms were determined from the geometric definitions of the trunk. b Plot shows exponential fit of DLP-normalized effective dose to chest diameter with comparison to data from Li et al.’s [25] protocol C for chest examination (120 kVp, large bowtie filter, pitch 1.375, 40-mm collimation) (dashed line). Data normalized to DLP from 32-cm-diameter phantom. DLP dose-length product
