Nominal kVp | First HVL1 (mm Al) | Second HVL (mm Al) | Homogeneity coefficient |
---|---|---|---|
60 | 2.31 | 3.06 | 0.753 |
70 | 2.65 | 3.78 | 0.700 |
80 | 3.00 | 4.42 | 0.678 |
100 | 3.82 | 5.76 | 0.663 |
120 | 4.53 | 7.03 | 0.645 |
HVL = half-value layer. All HVL were measured with Type 1100 aluminum.
