Table 2 Values of the coefficients of Eq. (2), (3), and (5) evaluated for the reference Hologic Selenia Dimensions (device A)

From: Average absorbed breast dose (2ABD): an easy radiation dose index for digital breast tomosynthesis

ParameterY0 at 32 kVp (mGy/mAs)α (mGy/(kVp2 ·mAs))β (mGy/(kVp·mAs))γ (mGy/mAs)a (kVp/cm)b (a.u.)
Value0.094 ± 0.005(5.70 ± 0.86)·10−5(3.77 ± 0.56)·10−3(− 8.44 ± 0.89)·10−220.32 ± 1.97− 1.04 ± 0.03
  1. Data are presented as mean ± standard deviation. These values were employed to calculate the incident air kerma and 2ABD. Notice that these values depend on the anode-filter combination (W-Al in our case)
