摘要： An X-ray computer tomography apparatus includes an X-ray tube, a two-dimensional array type X-ray detector, a rotating mechanism, a pair of collimators, a collimator moving mechanism which separately moves the pair of collimators in a direction almost parallel to a rotation axis, a reconstruction processing unit which reconstructs image data in a reconstruction range, and a collimator control unit. The collimator control unit controls the position of each collimator in accordance with the distance between an X-ray central plane corresponding to a cone angle 0° and an end face of the reconstruction range. The collimator moving mechanism moves each of the pair of collimators in the range from the outermost position corresponding to the maximum cone angle to the innermost position offset from a position corresponding to a cone angle of nearly 0° to the opposite side.

摘要： The angle of each collimator plate with respect to an X-ray focal point is determined by fitting the collimator plate in grooves formed in upper and lower supports each having an integral structure. In addition, the warpage of each collimator plate is corrected and its flatness is maintained by fitting the periphery of the collimator plate which is on the X-ray detector side in a corresponding groove of an abutment plate provided on the X-ray detection surface side of the upper and lower supports. Furthermore, each collimator plate is supported by the corresponding grooves of the upper and lower supports and the corresponding groove of the abutment plate at least three sides.

摘要： Provided herein is a non-contact type rotational position sensor which is allowed to achieve intensification of parts, miniaturization, simplification of assembly, and higher accuracy. A rotor (a permanent magnet) is mounted on a rotational shaft. A Hall IC is interposed between an upper stator and a lower stator which are magnetic plates. The Hall IC is sensitive to magnetic flux density which varies according to a rotational position of the rotor. In a housing incorporating the rotor and the Hall IC is provided integrally a connector provided with an external connection terminal. Conductors for connecting external connection terminals and input/output terminals of the Hall IC are embedded into the housing by insert-molding. One ends of conductors are exposed at a fixed position where the input/output terminals are present. The terminals of the Hall IC are guided by a guide and joined to the one ends of conductors.

摘要： A multi-slice X-ray CT scanner is provided to realize high resolution and a wide scanned region in a slice-thickness direction for an object. In the X-ray CT scanner, an X-ray beam for slice imaging is radiated toward an object and scanned in a predetermined slice-thickness direction, a direction orthogonal to the slice-thickness direction being defined as a channel direction. The scanner comprises a two-dimensional X-ray detector, a data acquisition system, and an electrically combining unit. The detector has a plurality of X-ray detecting elements arranged in a two-dimensional array of both rows in the slice-thickness direction and columns in the channel direction, the detecting elements of each row being arranged in unequal pitches. The data acquisition system has a plurality of data acquiring elements arranged in a two-dimensional array of rows and columns, acquiring signals detected by the two-dimensional X-ray detector, and producing digital data proportional to the detected signals. The electrically combining unit electrically combines more than two columns of all the columns in the array of the X-ray detecting elements into at least two columns of all the columns in the array of the data acquiring elements in accordance with a given slice imaging condition. For example, each row of the array of the data acquiring elements are less in number of elements than each row of the array of the X-ray detecting elements.
