  • Patent number: 7949383
    Abstract: An imaging box assembly is provided for capturing an image of a sample. The imaging box assembly includes a body having an interior cavity for receiving the sample, and having a front portion defining an opening into the cavity. The body further includes a view port enabling viewing of the sample contained in the interior cavity. A door is mounted to the body that is movable between an opened condition, enabling access to the interior cavity through the cavity opening, and a closed condition, positioning a door rear portion substantially adjacent the body front portion to prevent access through the cavity opening. The box assembly further includes a moveable stage disposed in the cavity interior that supports the sample. The moveable stage is adapted to selectively position the sample at a selected one of a plurality of positions relative to the view hole.
