Abstract: Provided is a method of manufacturing a laminated scintillator panel having a structure in which a scintillator layer and a non-scintillator layer are repeatedly laminated in a parallel direction perpendicular to incidence of radiation, characterized by including a step of joining the scintillator layer and the non-scintillator layer. The present invention provides a method of manufacturing a lattice-shaped laminated scintillator panel capable of enlarging the area and increasing the thickness with means completely different from a prior art in which a silicon wafer is used.

Abstract: A storage phosphor plate assembly includes at least one storage phosphor plate having a storage phosphor layer for storing X-ray information and a substrate layer on which the storage phosphor layer is provided. The substrate layer contains a permanent magnetic material, and a support plate contains a magnetic material, the at least one storage phosphor plate being held on the support plate due to magnetic forces. The invention further relates to an X ray cassette and a system for reading out storage phosphor plate. An easy and safe handling of storage phosphor plates of various sizes and/or forms, in particular during the read-out process in the read-out system, is achieved.

Abstract: A radiography imaging system for generating images of a pipe assembly includes a radiation source for emitting rays. The pipe assembly includes at least one of a pipe, tubing, and a weld. The radiation source includes a radioactive isotope having an activity level within a range between about 1 Curie and about 40 Curies. The radiation source is positioned adjacent a portion of the pipe assembly. A detector is positioned opposite the radiation source. The portion of the pipe assembly is positioned between the radiation source and the detector such that the rays interact with the portion of the pipe assembly and strike the detector. The detector includes an imaging plate that is activated by illumination with the rays with an exposure within a range between about 0.5 Curie-minute and about 5 Curie-minutes of radiation. The imaging plate has a thickness within a range between about 5 mm and about 15 mm. The detector further includes an imaging unit for generating images based on information from the imaging plate. The imaging unit has a pixel pitch that is within a range between about 25 microns and about 100 microns.
