Claim 1
Independent Claim
193 words
An x-ray marker device comprising: a unitary member having a first side and having only a single suction cup on said first side so as to temporarily secure said member to a substantially flat surface of an x-ray film holder; said unitary member further comprising a second side having a body member unitary with said single suction cup, so that said body member forms said second side of said unitary member and said suction cup forms said first side thereof; said unitary member being substantially transparent to x-ray radiation; an x-ray opaque indicium formed in said body member so as to cast a characteristic shadow on film in the film holder when subjected to x-ray radiation; said body member having an upper surface substantially conforming in diameter to the diameter of said single suction cup and facing outwardly from the x-ray film holder, so as to minimize the size of the x-ray marker device; and an annular groove formed on the exterior of said unitary member between said body member and said single suction cup for selectively receiving a hanger member, so as to facilitate storing said marker device when not in use.
