摘要： An apparatus for obtaining a long-length x-ray image of a subject, has an x-ray source and a first sensor that generates a first signal that indicates termination of x-ray emission from the x-ray source. A digital radiography detector is energizable to generate image data after receiving x-ray emission from the x-ray source. A detector transport apparatus is actuable in accordance with the first signal to translate the digital radiography detector from at least a first detector position to a second detector position for generating image data at each detector position. A processor in communication with the digital radiography detector obtains the image data of the subject that is generated from the detector.

摘要： An extracting step (step S1) extracts uninfluenced pixels with a relatively high degree of certainty, while avoiding influences of random quantum noise as much as possible. An approximate fluoroscopic image is obtained based on such uninfluenced pixels (step S2). Thus, accuracy of the approximate fluoroscopic image can be improved over that of the prior art. Therefore, a grid foil shadow image (step S3) and a foil shadow standard image (step S4) calculated successively based on the approximate fluoroscopic image have improved accuracy over the prior art. As a result, while inhibiting influences of random quantum noise, a foil shadow removed image can be obtained which is free from artifacts due to distortion of a synchronous grid.

摘要： According to a radiographic apparatus of this invention, parameters obtained on an assumption that an X-ray tube 2 is moved Wd×m, which is an integral multiple of pixel pitch Wd, in a B− direction opposite to B+ direction which is a direction of movement by Y-direction adjust screws of a moving mechanism, are corrected as parameters obtained when X-rays are emitted from the X-ray tube 2 in a state of a grid 6 having been moved Wd×m by the Y-direction adjust screws. This allows only the grid 6 to be moved without moving the X-ray tube 2. Therefore, parameters equivalent to the parameters which should be obtained when the X-ray tube 2 is moved are obtained by moving the grid 6, and position shifting can be reduced.

摘要： An X-ray device for irradiating a beam of X-rays on an object to capture an X-ray image of the object is smaller in size and weight than conventional ones. The X-ray device includes an X-ray tube for generating the beam of X-rays and irradiating the beam of X-rays on the object, a shutter arranged around an X-ray irradiation axis for regulating an X-ray irradiation region on which the beam of X-rays is irradiated through the object, and a visual indicator unit arranged on the shutter for movement together with the shutter, the visual indicator unit being designed to visually indicate the X-ray irradiation region. In the X-ray device, the X-ray irradiation region is visually indicated by laser light without having to use a lamp otherwise provided between the X-ray tube and the shutter.

摘要： To automate positioning operation of an X-ray tube so as to reduce the inspection time. Anatomical program selection means selects a surgery method/imaging object portion so that an imaging condition stored as an anatomical program in advance is called out and set in an X-ray generation device. Here, when an operation switch is pressed, control means moves drive means built in X-ray irradiation means parallel movement holding means and X-ray irradiation means rotation holding means so as to obtain the positional relationship between an X-ray tube and an FPD stored in correspondence with the anatomical program (such as SID and incident angle). The position of the FPD should be matched with the examinee. However, since the positional relationship between the X-ray tube and the FPD is almost constant in accordance with the surgery method/imaging object portion, it is possible to reduce the time required for positioning the X-ray tube by using this configuration.
