Abstract:
A radiographic marker system, comprising:a. a radiolucent base layer comprising an adhesive, said base layer formed in an enveloping shape, adapted to retain a marker adjacent structure to be imaged;b. a structure creating a layer of material substantially transparent to imaging radiation at energies used in radiographic imaging applications where the marker is used, the layer being formed in an enveloping shape and having a thickness extent;c. an imaging radiation absorbent marker opaque to imaging radiation at energies used in radiographic imaging applications where the marker is used, the imaging radiation absorbent marker being carried by the structure creating a layer of material transparent to imaging radiation said marker being configured to be substantially smaller in cross-sectional area presented to imagining radiation than that of said layer.
