三色塑料闪烁光纤在低剂量X射线探测和成像中的应用
Application of tricolor plastic scintillating fibers in low-dose X-ray detection and imaging
摘要
Abstract
This study aims to prepare plastic scintillating fibers(PSF)with excellent radiation dose response and radiation stability,as well as novel scintillating fiber arrays with outstanding X-ray imaging performance and multifunctional characteristics.Rare earth complexes and organic compounds were used as dopants,and the Teflon method was adopted to prepare red,green,and blue plastic scintillating fibers(marked as PSF-R,PSF-G,and PSF-B,respectively).By regulating the arrangement and geometric structure of the three-color plastic scintillating fibers,various types of plastic scintillating fiber arrays were prepared.PSF-R,PSF-G,and PSF-B all exhibit excellent radiation response characteristics,with dose detection limits of 0.555 μGy/s,2.775 μGy/s,and 2.22 μGy/s,respectively—all of which are lower than the standard dose for X-ray diagnosis(5.5 μGy/s).The prepared fiber arrays can effectively perform X-ray imaging on millimeter-scale objects.The plastic scintillating fibers and fiber arrays prepared in this study have significant application potential in the field of low-dose X-ray detection and imaging.关键词
