    Abstract: Apparatus for generating a high contrast image of a living subject includes an X-ray source capable of generating an X-ray beam having an energy between about 4 MeV and about 40 MeV, means for directing the X-ray beam generated by the X-ray source to a preselected area of the body of a living subject, and at least one scintillating detector capable of detecting photons which are generated as a result of the interaction of the X-ray beam with the body of the living subject.

    Abstract: 2122493 9309447 PCTABS00022 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, 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, with the claddings of the two fibers in optical contact at an intersection point. 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.
