The aim of the study is to compare the radiation dose of a clinical system for the acquisition of mammographic and tomosynthesis images. About 4000 exams are performed every year on adult female patients using the same device (Selenia Dimensions; Hologic, Bedford, MA, USA) that provides digital 2D and 3D images of the breast. We present the dose assessment performed by means of a radiation dose-tracking tool developed in our department that extracts data from the DICOM Header archived in our PACS. Average Glandular Dose (AGD) evaluated by the system is extracted by our dose-tracking tool.
