Multimaterial Fibers with Nanoemitters Enable Conformal X-ray Imaging with 3D Printed and Woven Scintillators

“…Additionally, the uneven spatial distribution of X-ray dose and the unavoidable oblique incidence of X-rays on flat scintillation screens lead to a considerable reduction in image quality. 18,25,26 Obliquely incident X-rays on flat scintillation screens result in a significant decrease in the spatial resolution of X-ray images. 26 Consequently, planar scintillators cannot provide details on the actual shape, spatial location, and size of nonplanar objects, even though such details are crucial for medical diagnostics, therapy, and materials inspection.…”

“…Therefore, X-rays have been extensively used for medical diagnostics and therapy, industrial material testing, scientific research, and security inspection. − Among different X-ray device architectures, indirect flat-panel X-ray detectors are currently one of the most common in use. − ,− These detectors usually consist of a planar scintillator coupled with an array of photodetectors. − Although flat-panel scintillation detectors can provide detailed two-dimensional projection images, these images often face distortion, because they are formed by projecting three-dimensional objects onto a two-dimensional plane. Additionally, the uneven spatial distribution of X-ray dose and the unavoidable oblique incidence of X-rays on flat scintillation screens lead to a considerable reduction in image quality. ,, Obliquely incident X-rays on flat scintillation screens result in a significant decrease in the spatial resolution of X-ray images . Consequently, planar scintillators cannot provide details on the actual shape, spatial location, and size of nonplanar objects, even though such details are crucial for medical diagnostics, therapy, and materials inspection.…”
