Figure 2
Exposure response for the H 1 and H 2 units. This shows exposure measured in milliampere seconds (mAs), the pixel value response, and fitted curves (solid) of the detector without attenuation for the H1 (left) and H2 (right) units. The measured values are averages represented by squares. The top plots show the W/Rh (target/filter) combinations acquired with 28 kV and the bottom plots show the W/Ag combinations acquired with 30 kV.
