  • Patent number: 9566036
    Abstract: A medical dose information management apparatus according to an embodiment includes a dose measuring unit, a dose graph generation unit, a dose graph generation unit, a display mode setting unit and an output unit. The dose measuring unit acquires dose information including an area dose in X-ray irradiation. The dose graph generation unit generates, based on the dose information, a dose graph indicating area doses respectively corresponding to imaging operations associated with the X-ray irradiation. The display mode setting unit sets a display mode for the dose graph in accordance with each of imaging schemes corresponding to the imaging operations included in the dose information. The output unit outputs the dose graph accompanied by the set display mode.

  • Patent number: 5930328
    Abstract: A versatile X-ray examination apparatus including a movable table top for supporting a patient, an imaging system having an X-ray source adopted for passing X-rays through the patient and an image receptor for generating an X-ray image of the patient, the image receptor is automatically moved to a desired position by a control system. The control system includes a memory for storing data concerning the table top, a control circuit for detecting a plurality of moving amounts of a plurality support members for supporting the imaging system, and a moving amount calculator for calculating a moving amount of the image receptor along a radiation axis on the basis of the data in the memory and the detected moving amount data provided from the control circuit.

  • Patent number: 5475885
    Abstract: A patient couch for an X-ray diagnosis comprises a base portion to be fixed to a floor of an X-ray diagnosis room and a movable portion mounted to the base portion to be movable with respect to the base portion and having a table top on which a patient lies. A tilting mechanism is secured to the base portion for vertically tilting the movable portion with respect to the base portion. The base portion and the tilting mechanism each has a width, in a width direction of the table top, smaller than a width of the table top and disposed below the movable portion along a longitudinal direction of the table top at a portion apart from a central axis thereof in the longitudinal direction so as to provide a space between a substantial portion of the movable portion and the floor. The tilting mechanism is tilted about a central axis, which is positioned below a horizontal level of the table top, by an angle more than 85.degree.

  • Patent number: 4731889
    Abstract: This invention provides a highly reliable safety device having a high fail-safe feature, which comprises a sector gear rotatably supported on a support base, a bed section supported on the sector gear and tiltable to a predetermined diagnostic angle anywhere from a horizontal position to a standing position of a patient, an off-normal rotation control means such as a limit switch to detect that the rotation of the sector gear relative to the support base exceeds the range of a limit rotation angle and to control its rotation, a hook member provided in a side surface position of the sector gear corresponding to the limit rotation angle beyond the off-normal rotation angle, a hook holding mechanism journaled in a side surface position of said support base which faces the sector gear, and adapted to engage with the hook member to restrict and prevent any further rotation of the sector gear, and whereby the bed section is positively restricted against any further tilting beyond its limit rotation angle, immediate
