X-ray shielding device
First Claim
1. An x-ray shielding device for use with an x-ray table having a top for supporting an examination subject and having x-ray imaging apparatus extending over said top and in spaced relationship therewith, said shielding device comprising:
- first elongated means for being disposed substantially between said table top and said imaging apparatus,a first group of x-ray shielding panels and rotatable means respectively supporting said panels from said first elongated means for rotation about the respective axes of the panels,a second elongated means pivotally connected to said first elongated means for being disposed alternately substantially in line with said first elongated means and at angles relative to it,a second group of x-ray shielding panels mounted to said second elongated means, andmeans responsive to pivoting of said second elongated means by rotating said rotatable means and the said first group of panels.

Abstract
On a diagnostic x-ray table, a first group of x-ray shielding panels are supported for rotation on a carrier and another group of panels are supported on a lever that is pivotally connected to the carrier. The lever may be aligned with the carrier to present the combined width of all panels across the front of a combination spot film and fluoroscopic device. Means responsive to pivoting the lever along the side of the apparatus rotate the first group of panels to substantial parallelism with second group to present the panels along the side of the apparatus when the spot film and fluoroscope device is angulated to put the patient being examined in an erect posture.

6. An x-ray shielding device for use with a tiltable x-ray table having a longitudinally extending table top and x-ray imaging apparatus extending laterally of the top in spaced relationship therewith and having a longitudinally disposed front end and a laterally disposed side, said device comprising:
-
groups of flexible x-ray shielding panels for being disposed selectively along the front and sides of said apparatus, guide track means for being mounted at the front of said apparatus and extending generally longitudinally, support means and means for engaging said support means with said guide track means for said support means to translate thereon, a plurality of rotatable means which are mounted for rotation on said support means and which respectively support the panels in one group, lever means pivotally connected with said support means, and panels in another group being disposed along said lever means and suspended therefrom, and driving means responding to pivoting of said lever means by rotating said rotatable means. - View Dependent Claims (7, 8, 9, 10)

11. An x-ray shielding device for use with a tiltable x-ray table which has a top for supporting an examination subject and x-ray imaging apparatus extending crosswise over said top and in spaced relationship therewith, said shielding device comprising:
-
first guide means mounted to said imaging apparatus and extending generally lengthwise of said table top, carrier means translatable on said guide means, a first group of x-ray shielding panels mounted to said carrier means, lever means pivotally connected with said carrier means, a second group of x-ray shielding panels mounted to said lever means, second guide means mounted to said imaging apparatus and extending generally crosswise of said table top, means that are translatable along said second guide means and means for alternately connecting and disconnecting said lever means to said translatable means, tilting of said table from a substantially horizontal position causing said carrier means to translate on said first guide means under the influence of gravity and, when said lever is connected, to pivot said lever means for translation on said second guide means for rearranging said panels relative to said apparatus. - View Dependent Claims (12, 13)
