Fig. 2 Graph of exponentially fitted curves shows relation for individual
views of compressed breast thickness and mean glandular dose for four-view
augmentation mammography in six groups. ID = implant-displaced view, IF =
implant-full view, 100 = 100-speed film, 190 = 190-speed film, MoMo =
molybdenum-molybdenum target-filter combination, MoRh = molybdenum-rhodium
target-filter combination, RhRh = rhodium-rhodium target-filter combination.
Mean glandular dose increases exponentially as breast thickness increases,
especially for implant-displaced views. Molybdenum-molybdenum target-filter
combinations have highest doses, and rhodium-rhodium have lowest. Mean
glandular dose is 35% lower for 190-than for 100-speed film.
