  • Publication number: 20200305813
    Abstract: An X-ray imaging apparatus includes a table, an imager configured to capture a plurality of X-ray images, a rotating mechanism, a moving mechanism, and an image processor. The image processor is configured to generate a long image by performing processing of varying magnifications of the plurality of X-ray images based on an amount of relative movement of the table and the imager and splicing the plurality of X-ray images when imaging is performed at a plurality of imaging positions in a state in which an optical axis of X-rays radiated from an X-ray irradiator is inclined with respect to the table.

  • Patent number: 10765392
    Abstract: This X-ray imaging apparatus is equipped with an image processing unit. The image processing unit obtains a first image with a marker reference position set in a first X-ray image and generate a second image in which a virtual marker image is superimposed at a corresponding position in a second X-ray image reflecting the change of a relative position from the marker reference position with respect to the second X-ray image different from the first X-ray image.

  • Publication number: 20190388044
    Abstract: An X-ray imaging apparatus achieves X-ray fluoroscopy and X-ray imaging in the larger range by combining a sliding action or rotation of an arcuate C-arm and an tilting-and-rolling of the table in combination. As noted while the C-arm suspends sliding after the C-arm slides in the sagittal direction, the table of the examination table tilts. Then, an angle ? between the axis line from the X-ray irradiation element 31 to the flat panel detector 32 and the surface of the table 11 coincides with the target angle at which the X-ray fluoroscopy and the X-ray imaging is carried out. Then after, the table moves in the longitudinal direction and lowers.

  • Publication number: 20190374191
    Abstract: An examination table system provides a table that is securely moved with no loss of visibility on a radiograph due to bending or tilting. The table is equipped with an accelerometer and is rotatable from a horizontal position during use while supporting a patient to be imaged. The table may be manually moved. The system allows easy table movement compensation that incorporates the projection of the accelerometer and a table gradient while obtaining a clear radiograph image.

  • Patent number: 10478144
    Abstract: An X-ray imaging apparatus enables to improve workability and a register of a pathway information on X-ray imaging. The X-ray imaging apparatus comprises a control element that control a driving element 5 so that the X-ray irradiation element to image a subject S and a table loading the subject S are relatively movable based on a pathway information that is pre-registered when imaging the subject S.

  • Publication number: 20190021689
    Abstract: An X-ray imaging apparatus is provided with a distance sensor for measuring an SSD which is a distance between a focal point of the X-ray tube and a surface of a subject M, an input unit for setting a reference SSD associated with an incident dose in which imaging is allowed, and a comparator for comparing an SSD at the time of imaging associated with the incident dose obtained by using the SD measured by the distance sensor and a reference SSD set by the input unit.

  • Publication number: 20180368792
    Abstract: An X-ray imaging apparatus includes an X-ray tube (1), an FPD (2), a holding unit (4) that holds the X-ray tube and the FPD, which face each other, a table (3) on which a subject is placed, and a control unit (5) that controls the movement of the holding unit so as to control an X-ray irradiation direction of the X-ray tube and an X-ray detection direction of the FPD in an interlocking response with a relative position of the table to the X-ray tube and the FPD or based on an operation during X-ray imaging, when the X-ray imaging apparatus performs the X-ray imaging while relatively moving the table with respect to the X-ray tube and the FPD.

  • Publication number: 20130028388
    Abstract: When a multi-system setting command switch, targeted rotating position information switches, and a command executing switch are pressed down, a CPU reads out a path of frontal and lateral systems from a current position to a setting position from a setting position information memory, and reads out rotation direction and angle from a targeted position information memory. The CPU moves the frontal and lateral systems horizontally along the read-out path until the commanded setting position information conforms to detected actual position information. When the setting position information conforms to the actual position information, the frontal and lateral systems are rotated successively until the commanded rotation direction and angle conform to the detected actual position information. Thereby a fluoroscopic X-ray system can be moved smoothly from a standby position via the setting position to a targeted rotating position.
