Comparison of mean glandular dose values provided by a digital breast tomosynthesis system in Brazil

•Studies are needed to determine the dose of tomosynthesis (DBT) procedures.•Mean glandular dose (DG) results derived from the incident air kerma (Ki).•Ki values were obtained through an ionization chamber.•A DBT system was used with appropriate exposure parameters.•This work contributes to compare DG values provided by this DBT system images.

Studies are needed to determine the radiation dose of patients that are undergoing Digital breast tomosynthesis (DBT) procedures. Mean glandular dose (DG) values were derived from the incident air kerma (Ki) measurements and tabulated conversion coefficients. Ki values were obtained through an ionization chamber positioned in a Hologic Selenia Dimensions system using appropriate exposure parameters. This work contributes to determine the reliable radiation dose received by the patients and compare DG values provided by this DBT system images.
