Abstract: The invention relates to a method and an imaging system (100) for generating X-ray 101a 101b 101c 101d images. The system (100) comprises at least one X-ray source, preferably an array of X-ray sources (101a-101d), and an X-ray detector (103) with an array of sensitive pixels (103a-103e). A collimator (102) is arranged between the X-ray source and the detector such that two openings (P) of the collimator (102) allow the passage of X-rays towards two neighboring pixels (103a-103e) while the region between said pixels is substantially shielded. This shielding of the usually insensitive regions between pixels reduces unnecessary X-ray exposure. A sufficiently large X-ray intensity can be achieved by using a plurality of small X-ray sources (101a-101d).

The electron emitting body has a substrate, the surface of which forms a concave surface, and a carbon film comprising a large number of projections made of carbon and expanded two-dimensionally.

Abstract: Fan beams of radiation are output from a multiplicity of radiation sources. Radiation is output simultaneously only from a part of the radiation sources having irradiation ranges that neither overlap with each other nor are adjacent to each other. Image correction data corresponding to each group of radiation sources is obtained by sequentially outputting radiation to the radiographic image detector while the groups of radiation sources are sequentially switched without setting a subject. An effective area that has a value higher than a predetermined threshold value is determined for each image correction data. Radiation is sequentially output to the radiographic image detector in a state in which a subject is set while groups of radiation sources are switched. Radiation image data obtained based on the effective area, and which corresponds to each of the groups of radiation sources, is corrected based on the image correction data.

Abstract: A tetrahedron beam computed tomography system including an x ray source array that sequentially emits a plurality of x ray beams at different positions along a scanning direction and a collimator that intercepts the plurality of x-ray beams so that a plurality of fan-shaped x-ray beams emanate from the collimator towards an object. The system includes a first detector receiving a first set of fan-shaped x ray beams after they pass through the object, the first detector generating a first imaging signal for each of the received first set of fan-shaped x-ray beams and a second detector receiving a second set of fan-shaped x ray beams after they pass through the object, the second detector generating a second imaging signal for each of the received second set of fan-shaped x-ray beams. Each detector and source pair form a tetrahedral volume. In other embodiments, the system may also have more than two detectors arrays and/or more than one source array. Each pair of source array and detector array forms a tetrahedral volume. Using multiple detector arrays and source arrays can increase field of view, reduce the length of detector and source arrays so that the imaging system is more compact and mobile.
