The case of the channeling radiation for electrons was considered in the previous work [Il. Th e use of the electrons for producing and detecting this type of radiation has the advantage that available electron beams have much smaller transverse phase space than thoseof the positrons. In addition, the intensity of radiation of electrons is somewhat larger in comparison to the positrons simply d...

We compared reconstruction algorithms [filtered back projection (FBP), maximum likelihood expectation maximization (MLEM), and the simultaneous iterative reconstruction technique (SIRT)] in terms of the radiation dose and image quality, for exploring the possibility of decreasing the radiation dose during digital breast tomosynthesis (DBT). The three algorithms were implemented using a DBT syst...
