    摘要: This invention has as its object to realize a radiation image sensing apparatus which can adjust (AEC-controls) the amount of incoming light or dose without requiring high-speed driving. Since a second photoelectric conversion element (108) which is used to detect the total dose of radiation that enters a conversion unit is formed independently of pixels having first conversion elements (101) that are formed in the conversion unit on a single substrate, the need for reading out the outputs from the first conversion elements (101) at high speed for the purpose of adjustment of the dose of incoming radiation can be obviated, and another sensor used to adjust the dose need not be added, thus simplifying the structure of a radiation image sensing apparatus.

    摘要: An X-ray imaging apparatus including an X-ray generation means for emitting X-rays, and an X-ray detector on which a grid selected from a plurality of different types of grids is removably mountable. The X-ray detector receives the X-rays emitted from the X-ray generation means, and obtains an X-ray image. The X-ray detector includes an automatic exposure control (AEC) detector for detecting the quantity of X-rays emitted from the X-ray generation means and for outputting a signal based on the detected quantity. The X-ray imaging apparatus also includes a control means for controlling the X-ray generation means and the AEC detector, where the control means controls the X-ray generation means based on the signal output from the AEC detector, and where the control means controls the AEC detector using correction data to correct an exposure detection element forming a part of the AEC detector.

    摘要: Image sensing radiation detection pixels of m (columns)×n (rows) are divided into, e.g., 72 pixel regions. Image sensing radiation detection pixels belonging to one pixel region are connected to the same read TCP and driving TCP. For example, three regions (AEC radiation detection regions) of the 72 pixel regions have a plurality of AEC radiation detection pixels. An AEC radiation detection pixel has a TFT sensor. Spare wiring lines for the AEC radiation detection pixels are arranged at two side portions of each read TCP. Each spare wiring line is connected to a predetermined circuit in a read device to connect the AEC radiation detection pixels to the predetermined circuit so that the AEC circuit is operated.
