ABSTRACT:
An apparatus that mounts on a standard dental x-ray film view box, and holds a moveable camera chassis with a high resolution CCD video board camera therein, is disclosed. The advantage of this invention is that users will be able to quickly, easily, and inexpensively convert a standard dental x-ray viewer into analog and/or digital x-ray image viewing systems, utilizing computer or video monitors. The camera chassis with CCD video board camera is mounted on tracks set on a line disposed to be parallel to both the X-axis and Y-axis of the plane of the translucent viewing plate of a standard dental x-ray viewer. The CCD video camera can slide over a target x-ray film placed thereon, for selective viewing on a video monitor or computer monitor. Additionally, the CCD video camera mechanism can be rotated up and away from the x-ray film set, which allows the dentist to visually scan the entire x-ray film set without visual obstruction. Users will also be able to utilize this device for enhanced diagnosis, and to show greatly enlarged and high resolution x-ray film images to patients for education and improved case presentation.
