  • Patent number: 10405812
    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.

  • Patent number: 10136871
    Abstract: 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.

  • Publication number: 20040251596
    Abstract: A cassette comprised of a box member adapted to house a sheet-shaped image medium therein, an access member, and a transport member. The box member is provided with an opening through which the medium can be fed into and out of the box member along a first direction. The access member is attached to the box member and movable about an axis substantially perpendicular to the first direction between a first position wherein the access member is disposed in the opening and a second position wherein the access member is not disposed in the opening. The transport member is disposed within the box member and translatable within the box member in the first direction to move the medium into and out of the box member through the opening when the access member is in the second position.

  • Patent number: 5522563
    Abstract: A film cassette comprises a pair of housing parts, and a flexibly movable latching hook located on one of the housing parts and a rigid latching catch located on the other housing part which can engage to secure the two housing parts together. According to the invention, a backer projects from one of the housing parts into abutment with the latching hook, when the latching hook and the latching catch are engaged, to prevent the latching hook from moving out of engagement with the latching catch in response to a mechanical shock being applied to the film cassette.

  • Patent number: 5452038
    Abstract: When a film cassette having a light shield that can be rotated open to permit film movement out of and into the cassette interior is loaded into a camera, a torsionally-compliant driver device of the camera for rotating the light shield open and closed is twisted, responsive to initial engagement with the light shield, to oppositely bias the light shield closed.

  • Patent number: 5359378
    Abstract: A film cassette comprises light blocking means supported for movement to a light blocking position for preventing ambient light from entering the cassette interior and to a non-blocking position. The light blocking means has a cavity for receiving a driver element in driving engagement to allow the driver element to move the light blocking means from its light blocking position to its non-blocking position. A locking pawl protrudes into the cavity to secure the light blocking means in its light blocking position and is adapted to be displaced from the cavity to release the light blocking means when the driver element is received in the cavity.

  • Patent number: 5295634
    Abstract: In a film cassette, a spool core about which a filmstrip is coiled is rotated in an unwinding direction to thrust a leading end portion of the filmstrip from inside to outside the cassette. The filmstrip has a trailing or inner end portion with a hole in it. The spool core includes a double-hook piece in the hole having a shorter hook and a longer hook. The shorter hook projects from the hole in the unwinding direction to slightly overlie the trailing end portion to engage the trailing end portion for pushing the filmstrip off the spool core to thrust the leading end portion outside the cassette when the spool core is rotated in the unwinding direction, but which will exit the hole as the trailing end portion begins to separate from the spool core.

  • Patent number: 5232175
    Abstract: In a film cartridge, a spool hub has a coaxial cavity in one end portion. A cartridge housing for the spool hub has a hole in one end wall that is aligned with the cavity to permit access to the cavity through the hole. A hermetic plug is sized to fit tightly in the hole to act as an airtight seal for the hole, but is sufficiently compliant to permit it to be forcibly pushed intact from the hole into the cavity to provide a visible indication that the film cartridge has been used.
