摘要： A radiation detector is provided that has no fluctuations in detection sensitivity and is capable of suppressing the influence of the noise emitted from a light source. In the radiation detector in the present invention, a light emitting unit applies light to the end face of a flat light guide. On receiving the light, the flat light guide emits flat light from its surface toward an active matrix substrate. The light is led to a semiconductor thick film after passing through the active matrix substrate. The noise emitted from the light emitting unit to the active matrix substrate or the semiconductor thick film can be blocked by an electromagnetic shield. An incident radiation to the semiconductor thick film in this condition can be detected while the effect of the noise emitted from the light emitting unit is suppressed, and fluctuations in radiation sensitivity do not occur.

摘要： A radiographic apparatus removes lag-behind parts from radiation detection signals taken from an FPD as X rays are emitted from an X-ray tube, on an assumption that the lag-behind part included in each X-ray detection signal is due to an impulse response formed of exponential functions, N in number, with different attenuation time constants. The lag-behind parts are removed by using impulse responses corresponding to variations in the sensor temperature of the FPD. X-ray images are created from corrected radiation detection signals with the lag-behind parts removed therefrom.

摘要： A subtraction image is obtained, by a subtraction process (DSA process), from a live image and a mask image. A lag-behind part included in each X-ray detection signal is considered due to an impulse response formed of exponential functions. The lag-behind part is removed from each X-ray detection signal by a recursive computation to obtain a corrected X-ray detection signal. The live image and mask image are obtained from such corrected detection signals.

摘要： A radiographic apparatus removes lag-behind parts from radiation detection signals taken from an FPD as X rays are emitted from an X-ray tube, on an assumption that the lag-behind part included in each X-ray detection signal is due to an impulse response formed of a plurality of exponential functions with different attenuation time constants. The lag-behind parts are removed by using impulse responses of the FPD corresponding, for example, to an X-ray dose used in a fluoroscopic image pickup and an X-ray dose used in a radiographic image pickup. X-ray images are created from corrected radiation detection signals with the lag-behind parts removed therefrom.

摘要： A TFT array is formed on a glass substrate (step P1). A surface protection layer is formed on the glass substrate so as to cover the TFT array (step P2). The glass substrate is divided to form active matrix substrates with the surface protection layer being provided (step P3). The divided active matrix substrate is chamfered along its edges (step P4). The surface protection layer is removed from the active matrix substrate (step P5). An X-ray conductive layer is formed on the TFT array where the surface protection layer has been removed (step P6). By these steps, pollutants produced during the division and chamfering of the glass substrate are prevented from polluting the TFT array and the X-ray conductive layer, and the active element array and the semiconductor layer is prevented from deteriorating in terms of performance in manufacturing process for a two-dimensional image detector.

摘要： A drive controller varies a bias voltage applied from a bias supply to a conversion layer based on the presence or absence of binning, that is, for a case of carrying out binning where switching elements are driven on the basis of a plurality of rows at a time by a gate drive circuit, and for a case of carrying out no binning where the switching elements are driven on a row-by-row basis by the gate drive circuit. Therefore, in the case of a fluoroscopic mode for acquiring images with binning, a lowering of a dynamic range can be suppressed. In the case of a radiographic mode with no binning, spatial resolution can be made high. That is, a high dynamic range and high spatial resolution can be optimized according to modes of operation.
摘要翻译：驱动控制器基于是否存在分档来改变从偏置电源施加到转换层的偏置电压，即，对于在基于多个行的驱动开关元件的情况下执行合并的情况，并且对于通过栅极驱动电路逐行驱动开关元件的情况下，不执行合并的情况。因此，在采用分档获取图像的透视模式的情况下，可以抑制动态范围的降低。在没有合并的射线照相模式的情况下，可以使空间分辨率高。也就是说，可以根据操作模式优化高动态范围和高空间分辨率。

摘要： A radiation detector of this invention has a curable synthetic resin film covering exposed surfaces of a radiation sensitive semiconductor layer, a carrier selective high resistance film and a common electrode, in which a material allowing no chloride to mix in is used in a manufacturing process of the curable synthetic resin film. This prevents pinholes and voids from being formed by chlorine ions in the carrier selective high resistance film and semiconductor layer. Also a protective film which does not transmit ionic materials may be provided between the exposed surface of the common electrode and the curable synthetic resin film, thereby to prevent the carrier selective high resistance film from being corroded by chlorine ions included in the curable synthetic resin film, and to prevent an increase of dark current flowing through the semiconductor layer.
