Abstract
This study investigates the impact in terms of radiation dose when performing simultaneous digital breast tomosynthesis
(DBT) and mechanical imaging (MI) – DBTMI. DBTMI has demonstrated the potential to increase specificity of cancer
detection, and reduce unnecessary biopsies, as compared to digital mammography (DM) screening. The presence of the
MI sensor during simultaneous image acquisition may increase the radiation dose when automatic exposure control is used.
In this project, a radiation dose study was conducted on clinically available breast imaging systems with and without the
MI sensor. We have investigated three approaches to analyse the dose increase in DBTMI, using (i) the estimates of average

This study investigates the impact in terms of radiation dose when performing simultaneous digital breast tomosynthesis
(DBT) and mechanical imaging (MI) – DBTMI. DBTMI has demonstrated the potential to increase specificity of cancer

MI sensor during simultaneous image acquisition may increase the radiation dose when automatic exposure control is used.
In this project, a radiation dose study was conducted on clinically available breast imaging systems with and without the
MI sensor. We have investigated three approaches to analyse the dose increase in DBTMI, using (i) the estimates of average
glandular dose (AGD) reported in DICOM headers of radiography images; (ii) AGD measured by a conventional
dosemeter; and (iii) AGD measured by optically stimulated luminescence using NaCl pellets. The relative increase in AGD
estimated from DICOM headers when using the MI sensor was on average 10.7% and 12.4%, for DM and DBT
measurements, respectively. The relative increase in AGD using the conventional dosemeter was 11.2% in DM mode and
12.2% in DBT mode. The relative increase in AGD using NaCl pellets was 14.6% in DM mode. Our measurements suggest
that the use of simultaneous breast radiography and MI increases the AGD by 13% on average. The increase in dose is still
below the acceptable values in mammography screening recommended by the European Guidelines.
