“…The investigation of patient specific breast models has been addressed by few research groups [25][26][27][28]. There is the need to better assess the influence of the texture and spatial location of the glandular tissue on the MGD estimates [8,25,29].…”

To provide mean glandular dose (MGD) estimates via Monte Carlo (MC) simulations as a function of the breast models and scan parameters in mammography, digital breast tomosynthesis (DBT) and dedicated breast CT (BCT). Methods: The MC code was based on GEANT4 toolkit. The simulated compressed breast was either a cylinder with a semi-circular section or ad hoc shaped for oblique view (MLO). In DBT we studied the influence of breast models and exam parameters on the T-factors (i.e. the conversion factor for the calculation of the MGD in DBT from that for a 0-degree projection), and in BCT we investigated the influence on the MGD estimates of the ion chamber volume used for the air kerma measurements. Results: In mammography, a model representative of a breast undergoing an MLO view exam did not produce substantial differences (0.4%) in MGD estimates, when compared to a conventional cranio-caudal (CC) view breast model. The beam half value layer did not present a significant influence on T-factors in DBT (< 0.8%), while the skin model presented significant influence on MGD estimates (up to 3.3% at 30 degrees scan angle), increasing for larger scan angles. We derived a correction factor for taking into account the different ion chamber volume used in MGD estimates in BCT. Conclusions: A series of MC code modules for MGD estimates in 2D and 3D breast imaging have been developed in order to take into account the most recent advances in breast models.

“…They can produce clinical outcomes data and avoid ethical issues and costs related to real clinical trials with a patient population. Generally, analytical approaches are usually adopted for breast projection computation [4][5][6][7] in order to keep the computational time and power consumption low, but in this approach photon scatter estimation is not usually taken into account. In order to overcome such limitation, recent research projects 8,9 have explored the possibility of simulating DM and Digital Breast Tomosynthesis (DBT) by means of Monte Carlo simulations.…”

“…Modern breast imaging techniques can be two-dimensional (digital mammography, dual energy and contrast-enhanced mammography, the advanced monochromatic, and phase-contrast imaging) or three-dimensional (tomosynthesis, and breast CT). Baneva Y. et al [17] presented the evaluation of a computational breast phantom, which closely mimics the structure (shape, dimensions, and content), and X-ray imaging characteristics of the corresponding real physical breast phantom for applications in mammography, and tomosynthesis.…”
