A radiographic imaging assistance device is provided. An acquisition component acquires position information representing positions of defective pixels of an imaging device, the imaging device being plurally provided with pixels comprising detection elements which detect radiation that has passed through a subject of imaging, and the imaging device carrying out imaging by generating image information which represents a radiographic image in accordance with radiation amounts detected by the detection elements and storing the image information in a pre-specified storage region. A judgment component, based on detection region information, which represents a detection region with a size corresponding to the subject of imaging, and the acquired position information, judges whether or not an influence from the defective pixels in a detection region that is represented by the detection region information is within an acceptable level that accepts imaging a radiographic image.

In a wireless IC tag, on which an integrated circuit and a small antenna are integrally mounted, a radiation-shielding material covers only the integrated circuit (IC chip) portion. Thus, the area of the small antenna covered by the radiation-shielding material is minute, and it is possible to minimally suppress a reduction in antenna gain of the small antenna. Such a wireless IC tag has radiation-shielding properties.

A method for manufacturing a thin-film solar cell substrate of group IB, IIIB and VIB elements of the Periodic Table, by using an apparatus for depositing selenium (Se) on the thin-film solar cell substrate. The apparatus has a base with gas inlet and outlet pipes. A bell jar is placed on top of the base with an O-ring interposed between them. A thin-film solar cell precursor and Se powder are placed in a recess formed in a lower heating jig, and the lower heating jig is positioned on the base. An upper heating jig is placed on top of the lower heating jig. The upper heating jig is vertically moved by a vertically actuating mechanism. The upper and lower heating jigs are heated under vacuum so as to diffuse Se to the thin-film solar cells, whereby a CuInSe2 alloy film is formed.

An air-fuel ratio detecting device with which the air-fuel ratio can be accurately detected over the entire range of ratios, both for the lean range and for the rich range. An oxygen pumping element and an oxygen sensing element are arranged opposite one another with a gap therebetween and are disposed in a chamber in which exhaust gas flows. A signal which is symmetric in lean and rich regions is thereby obtained, and this signal is divided into separate portions in the two regions, which are then composed to obtain a single-valued signal accurately representing the air-fuel ratio over the entire operating range.

摘要:
A source controller unit for controlling an x-ray source is provided with a detection signal interface for receiving detection signals from detective pixels of an electronic cassette or an integrated value of the detection signals only, or an interface for receiving a radiation stopping signal only. The source controller unit receives other radiation signals than the radiation stopping signal, such as a radiation admitting signal, through a radiation signal interface. The source controller unit uses the detection signals, the integrated value thereof, or the radiation stopping signal as exposure control signals for stopping radiation from the x-ray source. Since the exposure control signals are received on the specific interface therefor, the source controller unit does not need signal sorting operation nor receive different kinds of signals at the same time, improving the speed of radiation stopping procedure.
摘要:
In continuous radiography, while a patient stands in front of an imaging support, a total image capture field is determined. The total image capture field is divided into small image capture fields. A map scaling section scales up or down a full spine irradiation area map in accordance with the size of the total image capture field. A map dividing section divides the scaled map into small maps corresponding to the small image capture fields. In each division exposure, a detection pixel selector selects one or more detection pixels belonging to an irradiation area defined by the small map, out of all detection pixels distributed in an imaging surface of an electronic cassette. If an integration value of a detection signal from the selected detection pixel reaches a threshold value, X-ray emission is stopped. Division X-ray images obtained by the division exposures are merged into a single continuous X-ray image.

A compensation circuit 76 of an AEC unit 67 of an electronic cassette 13 defines the detection signal of a detection pixel 65 of the electronic cassette 13 as a detection signal corresponding to the detection signal of an old AEC sensor 25. The compensation circuit 76 performs compensation so as to exclude the influence on the detection signal due to a difference in the configuration of an intermediate member disposed between an X-ray source 10 and an FPD 35 of the electronic cassette 13 when the detection pixel 65 is used as an AEC sensor instead of the old AEC sensor 25. The detection signal is transmitted from a detection signal I/F 80 to a detection signal I/F 26 of a source control device 11 as it is (instantaneous value) or as an accumulated value obtained using an integration circuit 77.

摘要:
A portable radiographic imaging device and a portable X-ray source, that operate due to a first and second rechargeable battery respectively, can be accommodated in an accommodating case that is portable. While the accommodating case is being transported, a charging circuit provided in the accommodating case acquires electric power from a third rechargeable battery accommodated in the accommodating case, and charges the first and second rechargeable batteries. In this way, by accommodating the portable radiographic imaging device and the portable X-ray source in the accommodating case, the rechargeable batteries for the portable radiographic imaging device and the portable X-ray source are charged during transport.
