Purpose Digital breast tomosynthesis (DBT) is a limited-angle tomographic imaging modality that can be used for cancer screening in conjunction with full-field digital mammography (FFDM) or synthetic (SM). Currently, there are five commercial DBT systems have been approved by the U.S. FDA screening, all varying greatly design and protocol. Because different technical specifications, need quanti...

According to published data, the absorbed dose used for a CBCT image acquisition with Varian OBI v1.3 can be as high as 100 mGy. In 2008 Varian released a new OBI version (v1.4), which promised to reduce the imaging dose. In this study, absorbed doses used for CBCT image acquisitions with the default irradiation techniques of Varian OBI v1.3 and v1.4 are measured. TLDs are used to derive dose d...

The purpose of this study is to validate Eclipse's electron Monte Carlo algorithm (eMC) in heterogeneous phantoms using radiochromic films and EGSnrc as a reference Monte Carlo algorithm. Four heterogeneous phantoms are used in this study. Radiochromic films are inserted in these phantoms, including in heterogeneous media, and the measured relative dose distributions are compared to eMC calcula...
