  1. Data for 2ABD are presented as mean ± standard deviation. In DM modality, the W-Rh anode-filter combination was selected by the AEC system for a range of 2.5–6.5 cm of phantom thickness, while for a thickness of 7 cm and 7.5 cm the W-Ag (*) was automatically set. On the other hand, only the W-Al option was available for DBT
