    Abstract: L'invention concerne un radiochromatogramme à très haute résolution pour rayonnements ionisants.
    Le radiochromatogramme comporte au moins un réseau (R) constitué d'un ensemble d'éléments filiformes ou fibres optiques susceptible de permettre un repérage spatial d'une surface à analyser selon un repère d'axe déterminé et permettant d'assurer la détection par scintillation des rayonnements et la transmission du rayonnement lumineux produit par cette détection. Le réseau (R) est formé de deux nappes (N1) et (N2) constitué par des fibres optiques, chaque fibre étant respectivement disposée selon un segment de droite définissant deux directions (d1,d2) orthogonales délimitant un plan ou surface d'analyse. Au moins l'une des nappes (N1) est subdivisée en deux nappes élémentaires (N11, N12) espacées dans une direction perpendiculaire au plan ou surface d'analyse d'une distance (HP). Les fibres (fi11,fi12) constitutives d'une nappe élémentaire formant une nappe sont parallèles.

    Abstract: A fibrescope comprises a scintillator arranged to produce light of a first wavelength upon exposure to radiation; an optical system arranged to receive and direct light of the first wavelength emitted from the scintillator, the light being received at one end of the optical system, and wherein one or more elements of the optical system emits scintillation light of a second wavelength upon exposure to radiation; and an optical filter, disposed at the other end of the optical system, and arranged to transmit light of the first wavelength and block light of the second wavelength. The scintillator is chosen such that the light of the first wavelength is spectrally distinct from the light of the second wavelength.

    Abstract: An apparatus and method are disclosed for detecting and locating the origin of a gamma ray in a medical diagnostic imaging system. At least one primary fiber, which is a scintillating optical fiber, is positioned to receive radiation from a gamma ray source. At least one secondary fiber intersects the primary fiber at a non-zero angle and is in optical contact with the primary fiber. Both the primary and secondary fibers are provided with means for detecting light propagated in the fibers. The interaction of a gamma ray with the primary fiber will result in the propagation of light in both the primary and secondary fibers, thereby permitting the determination of the site of impact of the gamma ray in the detector, and possibly also enabling the determination of the path of incidence of the gamma ray.

    Abstract: An apparatus and method are disclosed for detecting and locating the origin of a gamma ray in a medical diagnostic imaging system. At least one primary fiber, which is a scintillating optical fiber (21) is positioned to receive radiation from a gamma ray source. At least one secondary fiber intersects the primary fiber at a non-zero angle. Both fibers have a core surrounded by a cladding (22, 23), with the claddings of the two fibers in optical contact at an intersection point (24). Both the primary and secondary fibers are provided with means for detecting light propagated in the fibers. The interaction of radiation such as a gamma ray with the primary fiber will result in the propagation of light in both the primary and secondary fibers, thereby permitting the determination of the site of impact of the gamma ray in the detector, and possibly also enabling the determination of the path of incidence of the gamma ray.

    Abstract: 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.
