Conventional scintillator-based X-ray imaging typically captures the fullspectral of X-ray photons without distinguishing their energy. However, theabsence of X-ray spectral information often results in insufficient imagecontrast, particularly for substances possessing similar atomic numbers anddensities. In this study, we present an innovative multi-energy X-raylinear-array detector that leverages side-illuminated X-ray scintillation usingemerging metal halide Cs3Cu2I5. The negligible self-absorption characteristicnot only improves the scintillation output but is also beneficial for improvingthe energy resolution for the side-illuminated scintillation scenarios. Byexploiting Beer's law, which governs the absorption of X-ray photons withdifferent energies, the incident X-ray spectral can be reconstructed byanalyzing the distribution of scintillation intensity when the scintillator isilluminated from the side. The relative error between the reconstructed andmeasured X-ray spectral was less than 5.63 %. Our method offers an additionalenergy-resolving capability for X-ray linear-array detectors commonly used incomputed tomography (CT) imaging setups, surpassing the capabilities ofconventional energy-integration approaches, all without requiring extrahardware components. A proof-of-concept multi-energy CT imaging systemfeaturing eight energy channels was successfully implemented. This studypresents a simple and efficient strategy for achieving multi-energy X-raydetection and CT imaging based on emerging metal halides.
