X-ray Lookup MuLin Summary
It is not reliable above 500keV.
It may return more than one energy if the material contains absorption edges.
Some of the energy solutions are easily eliminated if they are outside the x-ray source's operational range.
It gives the correct X-ray energy from the input linear attenuation of a known material provided that the reconstruction algorithm used to produce the CT slice is quantitative.
Solutions near absorption edge energies should be treated with caution since near-edge attenuation can be sensitive to an atom's chemical environment.
To test the confidence of the reported energies, check the solutions returned at the standard deviations of the image data.
