Claim 1
Independent Claim
206 words
The combination of a selective shielding device and a scintillation camera comprising three fastening elements secured in preselected locations on said camera, said shielding device being formed of a substantially oval shaped body having a predetermined length and a width substantially one half the size of said predetermined length, said body having a convex-shaped tip extending in the direction of said width of said body on the periphery of one side of said body, a pair of fastening elements secured to opposite sides of said body lying substantially along the length thereof, a third fastening element secured to said body lying substantially along the width thereof on a side of said body opposite said convex-shaped tip, said fastening elements on said camera and said fastening elements on said shielding device being capable of rapidly and adjustably mounting said shielding device to said camera at preselected locations thereon and said body of said shielding device being made of a vinyl coated lead material capable of blocking any radiation emitted by said camera, whereby the head of a patient located adjacent said camera and having a preselected area of said head positioned in front of said shielding device is prevented from receiving any radiation upon said preselected area.
