A new scintillating optical fiber is used in an array as a scintillator plate for imaging with high energy radiation, particles and the like. The scintillating optical fiber is an inner plastic core fiber which is transparent to visible radiation and has an index of refraction of about 1.45 or greater, and the inner plastic core fiber has a plastic cladding material which has an index of refraction less than that of the inner plastic core fiber. The inner plastic core fiber contains a polymeric matrix material; a metal moiety; and an organic fluorescent material. The scintillator plates are useful in producing high efficiency and high resolution radiographic systems for x-ray medical diagnosis or non-destructive inspection as well as non-destructive inspection with thermal neutrons. In medical x-ray applications, such as mammography, the need for lower doses of x-rays for a given image quality is met and exceeded by the higher detection efficiency of these scintillator plates and their associated electronic read-out system.
一种新型闪烁光纤在阵列中用作闪烁板,用于高能辐射、粒子等成像。闪烁光纤是一种内塑料芯光纤,对可见辐射透明,折射率约为 1.45 或更高,内塑料芯光纤具有塑料包层材料,其折射率小于内塑料芯光纤的折射率。内塑料芯光纤包含聚合物基体材料、金属分子和有机荧光材料。闪烁板可用于生产高效率、高分辨率的射线成像系统,用于 X 射线医疗诊断或非破坏性检查,以及热中子非破坏性检查。在医用 X 射线应用中,如乳房 X 射线照相术,由于这些闪烁板及其相关电子读出系统的探测效率较高,可以满足甚至超过在给定图像质量下对较低 X 射线剂量的需求。
