Table 2.

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

Parameter	Y0 at 32 kVp (mGy/mAs)	α (mGy/(kVp2 ·mAs))	β (mGy/(kVp·mAs))	γ (mGy/mAs)	a (kVp/cm)	b (a.u.)
Value	0.094 ± 0.005	(5.70 ± 0.86)·10−5	(3.77 ± 0.56)·10−3	(− 8.44 ± 0.89)·10−2	20.32 ± 1.97	− 1.04 ± 0.03

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)
