  • Method and apparatus for x-ray imaging and gain calibration of detector and detector bracket
    Patent number: 10888299
    Abstract: The present invention provides an X-ray detection device and an apparatus and method for calibrating an X-ray detector, the method for calibrating an X-ray detector comprising: retrieving a calibration parameter stored in the X-ray detector relative to the X-ray detector; and calibrating the X-ray detector according to the calibration parameter.
    Type: Grant

  • X-ray imaging apparatus
    Patent number: 7382866
    Abstract: With a view to providing an X-ray imaging apparatus having a projector-collimator capable of adjusting an irradiation position of a light beam easily and accurately, a first luminous flux is made a luminous flux present within an orthogonal plate orthogonal to a y-axis direction which is an orthogonal direction and a second luminous flux present within the orthogonal plane is reflected and moved within the orthogonal plane to produce a light beam. Consequently, an irradiation position of the light beam over a subject can be adjusted in an independent manner by movement ?y in the orthogonal direction with use of a first screw and movement ?x within the orthogonal plane with use of a second crew. As a result, adjustment of an X-ray irradiation field position by an operator can be effected not only easily but also with a high accuracy.
