摘要： A radiological image detection apparatus includes: a scintillator which is formed out of a group of columnar crystals in which crystals of a fluorescent material emitting fluorescence when irradiated with radiation have grown into columnar shapes; and a photodetector which detects the fluorescence emitted by the scintillator as an electric signal. Activator density in the scintillator varies between high density and low density repeatedly in a radiation travelling direction in at least a part of the scintillator. The activator density in each of front end portions and base end portions of the columnar crystals is lower than the high density.

摘要： A portable radiographic apparatus system reduces the number of types of spare rechargeable battery. A first rechargeable battery for operation of a portable radiographic apparatus has the same shape and characteristics as a second rechargeable battery for operation of a portable X-ray source. The first rechargeable battery and the second rechargeable battery are interchangeable. When, in order capture images during a visit to an individual's home or a visit to a nursing facility, the portable radiographic apparatus and the portable X-ray source are taken to the visit destination, spare rechargeable batteries must be taken in case of trouble with the rechargeable batteries. Because the first rechargeable battery and the second rechargeable battery are interchangeable, by bringing either the first rechargeable battery or the second rechargeable battery, trouble can be addressed if it arises. In this way, the number of types of spare rechargeable battery can be reduced.

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.

The case includes a plurality of members having a first member provided with a ceiling plate part through which light penetrates. The case houses the scintillator, the pixel array and the support in a lightproof inner space formed by combining the plurality of members. The scintillator and the pixel array are disposed between the first support and the ceiling plate part. The first support absorbs light of a wavelength region corresponding to a part of a wavelength region which is sensed by the pixel array.

摘要： An electronic cassette has a top plate, an anisotropic heat transfer plate, a detection panel, and a scintillator disposed in this order from an X-ray irradiation side. The scintillator converts X-rays transmitted through the top plate, the anisotropic heat transfer plate, and the detection panel into visible light. The detection panel performs photoelectric conversion of the visible light. The anisotropic heat transfer plate is composed of a lamination of first prepregs in which all carbon fibers are oriented in a heat flow direction. The top plate is composed of an alternate lamination of the first prepregs and second prepregs that have carbon fibers oriented in a signal line direction. Body heat of a patient is transferred to the top plate, and is transferred in the heat flow direction in the anisotropic heat transfer plate, and then is released from a housing through heat absorbing members.
