Optimization of energy window widths in basis material decomposition using a multi-window photon counting X-ray detector

This article discusses how to choose the energy window widths in the problem of basis material decomposition that uses a photon-counting detector which counts photons in several energy windows. Basis material decomposition provides information on object composition by extracting the energy- related information from the number of photons in different detector energy windows. We investigated several candidate energy window parameters in this work and aimed to optimize the performance of basis material decomposition.
