摘要： A mobile radiography system includes sensors to detect a tilt angle and or pitch angle of the system to prevent deployment of the extendable boom and/or column and/or prevent activation of a motor drive if the tilt angle or pitch angle exceeds a pre-set boundary.

摘要： An adjustable collimator includes a pair of knobs configured to adjust an aperture size by manipulating one or both of the knobs. The knobs may be disposed at opposite ends of a first shaft. The knobs may be configured to each adjust a same dimension of the aperture or to each adjust a different dimension of the aperture.

摘要： A mobile radiography system includes a wheeled transport frame and a vertical column mounted on the transport frame. A telescoping arm is attached to the vertical column and to an x-ray tube head. The telescoping arm allows an operator to rotate the tube head to a desired orientation and then to fix the tube head in the desired orientation without mechanical impact noise. A permanent magnet and an electromagnetic coil assembly allows an operator to easily and quietly control rotation of the tube head.

摘要： A cone beam computed tomography imaging system uses a C-shaped structure to revolve a source and detector around an imaging axis. To balance the system a counterweight is attached to the C-shaped structure at one end adjacent to the detector. The source is attached to another end of the C-shaped structure opposite the detector.

摘要： An apparatus for cone beam computed tomography can include a support structure, a scanner assembly coupled to the support structure for controlled movement in at least x, y and z orientations, the scanner assembly can include a DR detector configured to move along at least a portion of a detector path that extends at least partially around a scan volume with a distance D1 that is sufficiently long to allow the scan volume to be positioned within the detector path; a radiation source configured to move along at least a portion of a source path outside the detector path, the source path having a distance D2 greater than the distance D1, the distance D2 being sufficiently long to allow adequate radiation exposure of the scan volume for an image capture by the detector; and a first gap in the detector path.
