Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
159 words
A three dimensional X-ray opaque foreign body marker device for use in combination with an X-ray machine of the type wherein X-rays are produced by an X-ray tube and directed through a part of the human anatomy and onto a photographic plate sensitive to exposure by X-ray radiation, wherein the improvement comprises: a first X-ray opaque elongated member; a second X-ray opaque elongated member which is connected at substantially right angles to said first elongated member; and a third X-ray opaque elongated member which is connected to at least one of the other said elongated members substantially perpendicular to the plane defined by the intersection of said first and second elongated members, whereby X-rays from said Xray tube form an image of said marker device on said photographic plate from which an accurate determination of the location with respect to said marker device of an X-ray opaque foreign body disposed in part of said human anatomy can be made.
Claim 2
Dependent Claim
159 words
A three dimensional X-ray opaque foreign body marker device for use in combination with an X-ray machine of the type wherein X-rays are produced by an X-ray tube and directed through a part of the human anatomy and onto a photographic plate sensitive to exposure by X-ray radiation, wherein the improvement comprises: a first X-ray opaque elongated member; a second X-ray opaque elongated member which is connected at substantially right angles to said first elongated member; and a third X-ray opaque elongated member which is connected to at least one of the other said elongated members substantially perpendicular to the plane defined by the intersection of said first and second elongated members, whereby X-rays from said Xray tube form an image of said marker device on said photographic plate from which an accurate determination of the location with respect to said marker device of an X-ray opaque foreign body disposed in part of said human anatomy can be made.
Claim 3
Dependent Claim
25 words
A three dimensional X-ray opaque foreign body marker device as claimed in claim 1, including means for indicating a predetermined point on said marker device.
