From: End-to-end design of multicolor scintillators for enhanced energy resolution in X-ray imaging
X-rays from a typical broadband source (X-ray tube) are incident on the imaged specimen. The photons that pass through are absorbed in various depths of the multicolor scintillator, whose emissions create colored spots on the red-green-blue (RGB) detector. The detector image is fed into a clustering algorithm which identifies each cluster’s position, radius, and dominant color. This information is used to obtain the probability that the cluster was created by an X-ray photon from a given energy bin
