(a) Effective dose at each acquisition angle of chest tomosynthesis for the reference phantoms and (b) doses to lungs, breasts, and liver at each acquisition angle for the reference female phantom. Negative angles mean the x-ray tube is inferior to the pivot point. The effective dose was averaged across male and female reference phantoms as defined in ICRP publication 103. Doses to the three organs for both reference phantoms showed the same pattern, so only female data were plotted here. ED = effective dose.
