A mobile x-ray apparatus having wheels for manual transport and an x-ray tube support attached to a base. The apparatus may be rolled by pushing and/or pulling the base, the support, or the x-ray tube. A brake is associated with at least one of the wheels to prevent rolling the apparatus when manually positioning the x-ray tube. The brake may be engaged from an actuator on the tube head, on the support, or on the base.

Digital x-ray imaging apparatus and method

An apparatus captures radiographic images of an animal standing on the apparatus. A base portion supports the standing animal and a moveable x-ray source is mechanically attached to the base portion. A digital radiographic detector is also mechanically attached to the base portion, and the x-ray source and the detector are configured to capture a radiographic image or a scan of at least one of the legs of the animal.

Extremity imaging for animals

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 Dthat 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 Dgreater than the distance D, the distance Dbeing 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.

Extremity imaging apparatus for cone beam computed tomography

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.

Extremity imaging apparatus

A CBCT imaging system comprises a digital radiation detector and radiation source. A detector transport moves the detector along at least a portion of a first curved path and a radiation source transport moves the radiation source along at least a portion of a second curved source path. The detector is configured to travel at least a portion of the first curved path, and the radiation source is configured to travel at least a portion of the second curved path. The detector is configured to obtain a plurality of 2D projection images over a range of scan angles for reconstructing a 3D volume image using the plurality 2D projection images.

Head and neck imager

A mobile radiography apparatus has a wheeled transport frame and a sectioned vertical column mounted on the frame, defining a vertical axis and having a base section with a first vertical position relative to the vertical axis and at least a first movable section that is translatable to a variable vertical position along the vertical axis. A boom apparatus supports an x-ray source, wherein the boom apparatus is coupled to the first movable section for positioning of the x-ray source along the vertical axis and extends outward with respect to the sectioned vertical column for positioning of the x-ray source in a direction that is orthogonal to the vertical axis.

Mobile radiography unit having collapsible support column

A scanning apparatus for scanning a sheet as the sheet is transported in a substantially vertical transport direction. The scanning apparatus includes a scan housing; first, second, and third couplings; and a transport apparatus. The scan housing supports an optical scanning apparatus. The second and third couplings allow at least two degrees of rotation of the scan housing with respect to a horizontal axis and constrain movement of the scan housing in a substantially vertical transport direction. The transport apparatus is coupled to the scan housing for guiding the sheet past the scan housing in the substantially vertical transport direction.

Sheet scanning apparatus

A multicassette autoloader for vertically oriented storage phosphor cassettes includes a front, a back and opposite sides. The autoloader includes an input bin for receiving multiple vertically oriented storage phosphor cassettes stacked together in face-to-face contact, wherein the cassettes are oriented front-to-back with faces facing the autoloader sides, and wherein each of the cassettes contains a storage phosphor which is removable from the cassette; a storage phosphor read location at which a storage phosphor is removed from and replaced in a storage phosphor cassette positioned at the storage phosphor read location; and an output bin for receiving storage phosphor cassettes from the storage phosphor read location for subsequent removal. The input bin, the storage phosphor read location, and the output bin are configured in the autoloader such that the input bin and the output bin are side-by-side but spaced apart and the storage phosphor read location is positioned in a path between the input bin and the output bin.

Multicassette autoloader for a storage phosphor reader

A radiation imaging cassette. The cassette includes a housing, a latch member, and guide edges. The housing is adapted to house a stimulable phosphor sheet. The housing includes a light-protected region and an opening for extraction and/or insertion of the stimulable phosphor sheet. The latch member releasably engages the stimulable phosphor sheet to secure at least a portion of the stimulable phosphor sheet within the light-protected region. The edge guides are disposed within the housing and operate to guide movement of the stimulable phosphor sheet through the opening.

Radiation imaging cassette

A radiation image reading apparatus, including a cassette receiving section, a scanning section, an erase section, and a transport section. The cassette receiving section is adapted to receive a cassette housing a stimulable storage phosphor sheet. The transport section is adapted to transport the sheet along a substantially linear transport path to and from a travel end point in forward and reverse directions, respectively, through the scanning section and the erase section. The scanning section is coupled to the transport section and comprises: an excitation source for directing excitation energy of a first wavelength toward the sheet; a detector for receiving light excited from the sheet by the excitation energy; and a gimbaled mounting mechanism configured to register the scanning section to the surface of the sheet.

Apparatus for scanning stimulable phosphor medium

A storage phosphor reader includes a multicassette autoloader for vertically oriented storage phosphor cassettes, the autoloader having a front, back, and opposite sides. The autoloader includes an input bin for receiving multiple vertically oriented storage phosphor cassettes stacked together in face-to-face contact such that said cassette faces face front and back; wherein each of said cassettes contains a storage phosphor which is removable from said cassette; and an output bin located beside said input bin, said output bin having a storage phosphor read location at which a storage phosphor is removed from and replaced in a storage phosphor cassette positioned at said storage phosphor read location, and having an output region for read cassettes to be subsequently removed from said output bin.
