    Abstract: A radiographic imaging apparatus includes elongated rigid guide rails having equivalent symmetrical shapes. Carriages attached to the guide rails are configured to move along a length of the guide rails and to support a portion of the imaging apparatus and to facilitate movement thereof along the guide rails. A first type spherical bearing assembly allows a gimbaled connection thereto while allowing substantially no axial movement. A second type spherical bearing assembly allows a gimbaled connection thereto while allowing a limited amount of axial movement. Frame mounts are each attached to one of the first type and second type spherical bearing assemblies to facilitate movement having a one sided tolerance along the guide rails.

    Abstract: 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.

    Abstract: A mobile radiography system includes a wheeled transport frame and a vertical column mounted on the transport frame. A boom is attached to the vertical column and to an x-ray tube head. A boom carriage allows movement of the boom along a track in the vertical column and includes a magnetic mechanism to lock the boom in the track at a desired height. An electromagnetic coil in the boom carriage is configured to disable the magnetic lock mechanism to allow vertical movement of the boom along the track.

    Abstract: 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 includes a first section, a second section movable within the first section, and a third section movable within the second section. The first section and the second section each include a drag assembly configured to provide a drag force on the linearly movable section therewithin. The drag assemblies each include a friction material pressed against the linearly movable section to provide a constant drag force on the linearly movable section while it moves. A permanent pressure source presses the friction material against the linearly movable section.

    Abstract: An x-ray imaging apparatus revolves a digital radiation detector and a radiation source about an imaging area where a subject is positioned to be imaged. A housing encloses the source and the detector, and includes an open housing gap to allow movement of the subject into the imaging area by moving through the open gap. A housing extension may be deployed to close the housing gap and to enclose the detector as it revolves. Shielding assemblies prevent exterior access into the housing.

    Abstract: 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.
