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.

In order to prevent a scintillator of an information reading apparatus from being broken in a bonding step, a protective layer is formed so as to cover the scintillator so that the shape of the scintillator is not broken.

In a photoelectric conversion apparatus obtained by arranging and fixing a plurality of semiconductor element substrates onto a base with an adhesive, the levels of the upper surfaces of the substrates are adjusted with a desired thickness of the adhesive so as to set the upper surfaces within the same plane while the distance from the upper surface of the base to the semiconductor element surface of each substrate is kept to a design value, thereby realizing a photoelectric conversion apparatus constituted by a plurality of substrates arranged two-dimensionally, which eliminates level gaps between the substrate, and hence is free from problems such as a decrease in resolution, a deterioration in sensitivity, and peeling of a phosphor and the like.

摘要:
A radiographic apparatus capable of detecting radiation in a stable manner and in an amount suitable for a good image includes AEC detectors arranged in a stripe pattern in the space between pixels converting incident radiation into an electrical signal. The stripes of the AEC detectors are arranged so as not to be parallel to those stripes of an anti-scattering grid.

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.
