Improvement of medical imaging with enhanced light extraction of scintillators by integrated nanophotonics

Scintillators are important functional parts in x-ray and Υ-radiation medical imaging instruments, while the high refractive index of scintillation materials significantly reduced the light yield from the scintillators to the detectors, which limited acquired image quality. In this paper, we reviewed two ways to improve the light yield of scintillators via nano photonic devices based on different scintillation materials and integrated nano structures.
