Table 1 Yield Y 0 (mGy · mAs–1) of the reference device and α (mGy · mAs–1 · kVp–1) and β (mGy · mAs–1) for the five anode-filter combinations considered. The average value ± 1 standard deviation of five measurements of Y 0 for each anode-filter combination are reported. These measurements were performed at 28 kVp
