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： A multi-channel type solid-state X-ray detector includes a base plate, multi-channel photodiodes arranged on the upper surface of the base plate and having one ends connected as output terminals to electrically conductive lines on the base plate, and a number of scintillators disposed on the photodiodes of respective channels, for generating scintillation light corresponding to incident X-rays when the X-rays are irradiated. Those end portions of the scintillators which lie on the other ends of the photodiodes are extended and a light emitting diode arranged in a flat plate configuration is disposed in contact with the underside of the extended portions on the upper surface of the base plate. The scintillators are shielded with respect to light on portions other than the underside which is in contact with the light emitting diode and photodiodes by reflective coating material or the like, and light from the light emitting diode is permitting to be projected into the entire portion of the scintillators. The light projection compensates for radiation damage of the scintillators and prevents the detection sensitivity of the scintillators from being lowered.

摘要： In an X-ray computerized tomography apparatus, a water phantom is interposed between an X-ray tube unit and an X-ray detector in place of a subject under examination and a plurality of pieces of data detected by a plurality of X-ray detector elements are previously measured as a pieces of compensation data while shifting the X-focal point to different positions. Compensation data corresponding to the actual position of the X-ray focal point, which shifts according to the thermal state of the X-ray tube unit, is selected to correct detect data obtained for a subject under examination, permitting optimum compensation of variations in sensitivity among the X-ray detector elements for any position of the X-ray focal point, thereby preventing a ring-like artifact from being produced on a tomography image.

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： A method for producing an activated carbon material, wherein the method comprises a step of thermally treating coal-based pitch at two temperature ranges of 400° C. to 600° C. and 600° C. to 900° C.; and a step of mixing the thus obtained carbonaceous material with an alkali metal compound and effecting activation thereof at 600° C. to 900° C., and an activated carbon material obtained by the method. When the activated carbon material of the present invention is used a polarizable electrode material of an electric double layer capacitor, high capacitance per electrode is attained without application of excessive voltage. By adding fibrous material to a coal-based pitch during activation expansion of an alkali molten liquid can be suppressed and productivity can be drastically improved. Furthermore, employment of an fibrous carbon material which is excellent in conductivity as a fibrous material, carbon fiber is melt-bonded on the surface of the activated carbon material, which enables production of a polarizable electrode exhibiting excellent charge/discharge characteristics at high current density.
