    Abstract: The present invention provides a multi-view X-ray inspection system. In one embodiment, a beam steering mechanism directs the electron beam from an X-ray source to multiple production targets which generate X-rays for scanning which are subsequently detected by a plurality of detectors to produce multiple image slices (views). The system is adapted for use in CT systems. In one embodiment of a CT system, an electron beam generated by a single radiation source is steered by an electron beam transport mechanism comprising at least two dipoles and a quadrupole on to a target arranged in an approximated arc. The inspection system, in any configuration, can be deployed inside a vehicle for use as a mobile detection system.

    Abstract: A method is disclosed for positioning a body region of interest of a patient in the isocentre of the imaging system of a computer tomograph or C-arm device. The method involves using the computer tomograph or C-arm device to record a topogram of the patient, determining a distance between the body region of interest and the isocentre from the topogram, and shifting a patient positioning device or the imaging system by this distance in order to move the body part into the isocentre. In the proposed method, the topogram is recorded in sections from various directions that are perpendicular to one another. The method enables the body region of interest to be positioned without the use of any external aids.

  • Publication number: 20140270059
    Abstract: Embodiments of the systems and methods of this disclosure utilize different positions, or poses, of a target object to collect images that can result in high-resolution volumetric models of the target object. In one embodiment, the object poses define a lateral position and an axial position (also “angular orientation”) of the target object relative to components of an imaging system, e.g., the source of the x-ray beam. The imaging system captures an image of the target object in the object poses. Further processing of the image data that relates to the images generates a volumetric model of the target object at higher resolution, or with fewer artifacts, as compared to similar volumetric models that arise from conventional scanning of these large parts.

When a descending instruction is issued, a bed controller controls the bed driver to descend the table top to the target return position stored in the storage unit.

  • Patent number: 8693623
    Abstract: The present invention relates to medical radiography, in which individual images of an object are taken at different projection angles and a 3D image subsequently synthesized from this image information. The object to be imaged is arranged locked in an object positioning means and during the imaging process, the x-ray source is continuously moved with respect to location of the object. During the continuous movement of the x-ray source there are irradiation periods and non-irradiation periods and during an irradiation period, the object positioning means is moved as synchronized with the movement of the x-ray source so as to follow the movement of the x-ray source.

  • Patent number: 8692213
    Abstract: One or more techniques and/or systems are described herein for handling an examination surface for radiology or other operations. That is, an examination surface support structure can be integrally coupled with a support component of a radiology apparatus so that an examination surface and an object optionally placed thereon are supported during an operation. An examination surface transport component can be docked with an examination surface docking component that is operably coupled with the examination surface support structure so that the examination surface can be exchanged between the transport component and the radiology apparatus. An examination surface transit component that is operably coupled with the examination surface support structure can engage the examination surface in order to move the examination surface into and out of an operation region of the apparatus, such as during a scanning or dosage operation.

  • Patent number: 8649480
    Abstract: When the diagnostic center position and a reconstruction FOV are designated using a tomographic image, a system control device controls a top plate of a table to move from side to side and up and down so that the designated diagnostic center position reaches the center position of scanning. A scanner is provided with a plurality of compensation filters configured to adjust X-ray irradiation distribution, and the system control device selects a proper compensation filter according to the designated reconstruction FOV from among the plurality of compensation filters, switching to the selected compensation filter. The compensation filters include at least a compensation filter (size L) of wide-width X-ray irradiation distribution and a compensation filter (size S) of narrow-width X-ray irradiation distribution in a scanner-turning direction. When the designated reconstruction FOV is a predetermined threshold or less, the compensation filter is switched to the S-sized compensation filter.
