  • Patent number: 10321887
    Abstract: In an image analysis device, an image analysis method, and a non-transitory computer-readable recording medium, it is determined whether a radiographic image is captured by rocking a rocking imaging grid. The image analysis device includes: a radiographic image acquisition section; a dosage data acquisition section that acquires dosage data indicating, in a time-series manner, a dosage of radiation rays exposed to a specific position in an imaging area in a specific period; and a determining section that determines whether the dosage data has a first feature indicating a dosage variation as a plurality of radiation absorbing bodies and a radiation transmitting body disposed between adjacent radiation absorbing bodies pass through a space between the specific position and a radiation source, and determines that the radiographic image corresponding to the dosage data determined to have the first feature is a rocking grid use image captured by rocking a rocking imaging grid.

  • Patent number: 9316750
    Abstract: A radiation image capturing system includes a radiation source and a radiation image detecting device. The radiation image detecting device includes a solid-state detector and a wavelength conversion layer disposed in this order from a radiation incident side. The wavelength conversion layer has a first phosphor layer having first phosphor particles dispersed in a binder, and a second phosphor layer having second phosphor particles dispersed in a binder. The average particle diameter of the second phosphor particles is smaller than that of the first phosphor particles. The first phosphor layer is disposed on the side of the solid-state detector relative to the second phosphor layer, and joined to or pressed against the solid-state detector. The first and second phosphor particles are distributed in the first and second phosphor layers, respectively, such that the weight of the binder per unit thickness is gradually decreased to the side of the solid-state detector.

  • Patent number: 7439523
    Abstract: A radiation image storage panel composed of a substrate and a layer of stimulable phosphor is prepared in an evaporation chamber kept at a pressure of 0.1 to 10 Pa by the steps of heating a source of the stimulable phosphor in the chamber so that the source is evaporated to give a gaseous product and depositing the gaseous product on the substrate which is arranged above the source to form the layer of stimulable phosphor on the substrate, in which the evaporation chamber has a diffusion preventing wall member surrounding a space between the source and the substrate, a top of which is positioned in the vicinity of a periphery of the substrate and a bottom of which is positioned in the vicinity of the source; and the diffusion preventing wall member is maintained at a temperature lower than a temperature of the source and higher than a temperature of the substrate.

  • Patent number: 7417237
    Abstract: The radiographic image conversion panel for mammography includes a phosphor layer formed on a rectangular substrate having first and second pairs of two parallel sides, and sealed with a moisture-proof protective film. The phosphor layer is positioned on the substrate such that a distance from at least one side of the first pair to an adjacent end of the phosphor layer is shorter than a critical bonding length being a shortest bonding length long enough to provide a predetermined level of moisture-proof effect and distances from two sides of the second pair to adjacent ends of the phosphor layer are not shorter than the critical length. A seal bonding layer is formed in areas of the second distance, and on a side surface having the at least one side or on the side surface and a rear surface of the substrate. The phosphor layer may be formed in a recess formed in the substrate.
