Fluoroscopy orientation device
First Claim
1. A device for assisting an operator of a fluoroscope in orienting said fluoroscope on an object during a fluoroscopic examination, said fluoroscope comprising a fluoroscopic x-ray emission tube, a receiver tube, and a monitor operatively coupled to said receiver tube for displaying a radiographic image of an internal structure of said object, which device comprises:
- a sheet transparent to x-ray radiation, said sheet possessing orientation indication means; and
means for positioning said sheet between said object and said receiver tube, said positioning means being attached to said fluoroscope;
wherein a surface of said x-ray transparent sheet contains a cavity for receiving an x-ray transparent disc and means for securing said disc in said cavity, said disc possessing said orientation indication means.

Abstract
A device for assisting a fluoroscope operator in orienting a fluoroscope on an object during a fluoroscope examination, and thereby reduce the time of use and exposure to radiation, which device consists of a sheet transparent to x-ray radiation, preferably disc shaped, possessing orientation indication means, such as radiopaque symbols, numbers and letters which may be combined in any combination. The orientation device is mounted on the fluoroscope'"'"'s receiver, thereby positioning the sheet and orientation indicators between the receiver tube and the object being examined. The orientation indicators are visible on the fluoroscope'"'"'s monitor, clearly indicating direction and providing guidance for the fluoroscope operator during the examination.

12. A device for assisting in orienting a fluoroscope on an object during fluoroscopic examination, said fluoroscope comprising a fluoroscopic x-ray emission tube, a receiver tube, and a monitor operatively coupled to said receiver tube, for displaying a radiographic image of the internal structure of said object, which device comprises:
-
an x-ray radiation transparent disc with a circumferential outer edge; radiopaque symbols; means for securing said symbols to said disc, thereby indicating an orientation; and means for removably attaching said disc to said receiver tube, said attaching means positioning said disc between said object and said receiver tube so as to permit said orientation symbols to be perceived on said monitor during operation of said fluoroscope; wherein said means for securing said symbols to said disc comprises a radiolucent tab;
a slot in a side of said sheet for securing said radiolucent tab; and
radiopaque symbols affixed to said tab. - View Dependent Claims (13, 14, 15, 16, 17, 18)
