Table 2 Comparison between k a,i (mGy) measured (k a,i meas ) and calculated by Equation 4 (k a,i calc ) for different mammography units. Y tb (mGy · mAs–1) is the yield of the mammographic device (calculated at 28 kVp, different for each anode-filter combination) and d (cm) is the breast thickness simulated by different solid-water phantoms. FID is the focus-image distance (cm) for the device considered
