We present a technique to simplify the calibration procedure of the dual‐energy scanning, using aluminum (AL) and plastic (PL) as basis materials. In essence, this method determines the “basis functions” of the basis materials at the chosen energies. This technique replaces the two‐dimensional calibration procedure, which is tedious, by two simple one‐dimensional calibration steps. In addition, this technique also provides an alternative approach for solving the dual‐energy problem.
