    摘要: To read stable image information by making small in a short time the amount of change in potential at the time the potential of signal wires or sensor bias wires drops a moment, the device is, in the refresh mode of photoelectric conversion pixels, so driven that the timing at which two drive wires are driven overlaps which are sequentially and at least consecutively driven by the control means among drive wires while keeping the signal wires at a reset potential.

    摘要: An object rotating type cone beam radiation CT radiographing device in which a high speed and high sensitivity are obtained with low costs is provided. Thus, a radiation CT device of high performance for vehicle-mounted use and group medical examination can be provided at low costs. In the object rotating type cone beam radiation CT radiographing device, a rotational angle of an object is detected, a signal storage period of a batch-exposure type radiation image sensor panel is controlled on the basis of the rotational angle signal, and a signal storage period of a signal storage type reference signal generator is controlled. There is provided a radiation CT radiographing device in which the object can be photographed at arbitrary resolution during the photographing, a fluctuation of a radiation source during the photographing can be detected without using a special detector and corrected in accordance with its detection amount.

    摘要: Disclosed is a technology for obtaining a large area fiber plate suited for downsizing a radiation imaging apparatus and reducing its cost and excellent of workability in the manufacturing process. A multi-fiber is manufactured by bundling and drawing a plurality of fibers to take a polygonal shape in section so that the multi-fibers can be air-tightly stacked without any air gap, a multi-fiber aggregate is manufactured by bundling and drawing the multi-fibers to take other polygonal shape in section that enables air-tight stacking with no air gap so as to be analogous to or different from the one polygonal shape in section, and there is manufactured a fiber plate configured by air-tightly bonding the multi-fiber aggregates to each other with a bonding agent without the air gap in a state of keeping the one or other polygonal shape in section after being drawn.
