Marking grid for radiographic imaging, and method of making such a grid
First Claim
1. A marking grid for use in radiographic imaging, comprising:
- a substrate, the substrate having a front side and a back side, the back side being coated with a pressure sensitive adhesive;
a plurality of elongated, substantially parallel strips of material fixed to the front side of the substrate and spaced relative to each other, each strip being made from a material that is at least partially radiopaque; and
a plurality of elongated apertures formed through the substrate between the strips, wherein a plurality of the elongated apertures extend laterally between adjacent strips and extend in the elongated direction of the strips along a substantial portion of the length of at least one adjacent strip.

Abstract
A marking grid is provided for use in radiographic imaging, and a method is provided for manufacturing the marking grid. The marking grid is comprised of a radiolucent substrate with a pressure sensitive adhesive on one side, a plurality of parallel strips of radiopaque material fixed to the substrate on the side opposite the pressure sensitive adhesive, and apertures in the substrate between the parallel strips of radiopaque material. The substrate is provided on a releasable backing with a plurality of holes longitudinally spaced relative to each other, which can be used to register the position of the substrate in the equipment used to produce the marking grids.

22. A marking grid for use in radiographic imaging, comprising:
-
a substrate defining a front side and a back side;
first means superimposed over the back side of the substrate for releasably attaching the substrate to a patient'"'"'s skin;
a plurality of second means fixedly secured on the front side of the substrate and formed of a material that is at least partially radiopaque for marking a patient'"'"'s skin on a radiographic image, wherein the plurality of second means are laterally spaced relative to each other and extend in an elongated direction from approximately one side of the substrate to the other; and
a plurality of third means formed through the substrate between the second means and extending in the elongated direction along a substantial portion of the length of at least one adjacent second means for permitting at least one of a marking instrument and a biopsy instrument to be inserted therethrough onto the patient'"'"'s skin underlying the marking grid. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method for making a marking grid for radiographic imaging, comprising the steps of:
-
providing a substrate attached to a releasable backing, the substrate having a front side and a back side, the back side being releasably attached to the releasable backing, and the releasable backing defining a plurality of apertures spaced relative to each other along at least one marginal portion thereof;
registering the substrate and backing with at least one of a tool for cutting the substrate and a tool for applying a material that is at least partially radiopaque to the substrate by engaging the apertures in the backing with at least one rotatably driven drive member registered with said at least one tool; and
moving the substrate and backing relative to the at least one tool by rotatably driving the drive member and moving the tool relative to the substrate to perform at least one of the following additional steps;
(a) applying a material that is at least partially radiopaque to the substrate at predetermined locations on the substrate, and (b) forming apertures in the substrate and extending between the predetermined locations of radiopaque material on the substrate.
