X-ray attenuation behaviour of Rh and Ni. Linear attenuation coefficient of rhodium and nickel as a function of energy are plotted together with the ΔE − and ΔE + of the Ross filter pairs. The K-edge energy of Rh (red solid line) sits between low-, ΔE −, and high spectral band, ΔE +, while it is not the case for Ni (green dashed dotted line).
