Multi-energy X-ray Imaging Based on Scintillator Encoders

Abstract X-ray imaging technology serves as a core tool in medical diagnosis and industrial non-destructive testing where imaging quality directly impacts diagnostic accuracy and detection precision.However traditional X-ray imaging technology is limited by its energy-integrating detection mode resulting in insufficient imaging contrast in complex scenari os.To overcome this technical bottleneck multispectral X-ray imaging technology has emerged.This paper focuses on multi-energy X-ray imaging technology based on scintillator encoders detailing multispectral detectors utilizing stacked scintillator encoding and side-incident depth information extraction.By thoroughly analyzing key technical aspects such as material selection and preparation device structure design and algorithmic analysis the principles characteristics and research progress of this technology are comprehensively explored.The paper summarizes existing achievements and cur rent challenges while also providing insights into future development trends aiming to offer theoretical guidance and practical references for further research and engineering applications of multispectral X-ray imaging technology.
