摘要： A scintillator receives radiation and produces light. The scintillator is composed of columnar crystals arranged upright. Conical end portions of the columnar crystals are embedded in a resin layer formed on a light detection section. The resin layer, made from a thermosetting resin material, is heated and cured with the end portions embedded therein. Because a refractive index of the resin layer is lower than that of the columnar crystals, average refractive indices of respective layers between the columnar crystals and the light detection section change continuously. The resin layer prevents the end portions from damage and improves efficiency of incidence on the light detection section.

摘要： A radiation detector includes a sensor panel, a scintillator panel, a reflective layer, and a radiation irradiation detecting photodetector laminated in this order from a side of a radiation receiving surface. Radiation transmitted through a patient's body enters the scintillator panel through the sensor panel, and is converted into light. The converted light propagates through columnar crystals in the scintillator panel with total internal reflection. Apart of the light reaches the sensor panel, while the remains reach the reflective layer. The light reaching the sensor panel is detected by photoelectric converters. Out of the light reaching the reflective layer, a short wavelength component with a relatively high refractive index is specularly reflected to the sensor panel. A long wavelength component with a relatively low refractive index is transmitted through the reflective layer, and enters the radiation irradiation detecting photodetector, which detects a start of radiation irradiation.

摘要： In a radiation detector, a scintillator converts radiations penetrating through a sensor panel to light, and the light is detected by a photosensor in the sensor panel. A reflector layer including a specular reflection and retro-reflection layers is provided on the opposite side of the scintillator to the sensor panel. The specular reflection layer specularly reflects short-wavelength components of the light from the scintillator, and lets long-wavelength components of the light pass through it. The photosensor can detect the short-wavelength components efficiently at positions close to their origins because they are guided along columnar crystals of the scintillator. Since long-wavelength components are less refrangible and tend to deviate from their origins, causing crosstalk, the retro-reflection layer retroreflects the long-wavelength components toward the sensor panel, so that the long-wavelength components also reach the sensor panel at positions close to their origins.

摘要： A radiographic image capture device includes a radiation detector, an application section and a controller. The radiation detector includes plural detection pixels that detect a radiation application state and plural imaging pixels that capture a radiographic image. The application section applies a bias voltage to each of the plural detection pixels and to each of the plural imaging pixels. The controller effects control such that, if the radiation application amount detected by the detection pixels is equal to or greater than a first threshold value during a first state in which the bias voltage is applied to the plural detection pixels, the application section is caused to transition to a second state in which the bias voltage applied to the detection pixels is reduced.
