Abstract
A multi-density skin marker for medical imaging exams is provided. The skin marker contains a multi-density imaging body. In one embodiment, a multi-density skin marker includes a marker substrate and a multi-density imaging body supported by the marker substrate. The multi-density imaging body comprises a first portion having a first radiographic density and a second portion having a second radiographic density. The two radiographic densities differ, such that a radiographic image of the multi-density skin marker comprises a plurality of shades.
Claims28
A multi-density skin marker comprising:
- a marker substrate;
- and
- a multi-density imaging body supported by the marker substrate, wherein the multi-density imaging body comprises a first portion having a first radiographic density and a second portion having a second radiographic density, and wherein the first radiographic density differs from the second radiographic density such that a radiographic image of the multi-density skin marker comprises a plurality of shades.
A multi-density skin marker comprising:
- a marker substrate having an adhesive surface;
- and
- a multi-density imaging body supported by the marker substrate and comprising a first imaging shape and a second imaging shape adhered to and at least partially overlapping the first imaging shape.
A multi-density radiographic image of a multi-density skin marker having a first portion with a first radiographic density and a second portion with a second radiographic density that differs from the first radiographic density, comprising:
- a first image of the first portion having a first shade;
- and
- a second image of the second portion having a second shade different from the first shade.
A method of using a multi-density skin marker for a radiographic imaging exam, comprising:
- locating an area of interest on a patient's skin;
- adhering to the patient's skin near the area of interest a multi-density skin marker having a first portion with a first radiographic density and a second portion with a second radiographic density that differs from the first radiographic density;
- and
- obtaining a multi-density radiographic image of the area of interest and the multi-density skin marker.
A method of manufacturing a multi-density skin marker, comprising:
- cutting a first outer perimeter of a first imaging body from a first radiolucent material;
- cutting a second outer perimeter of a second imaging body from a second radiolucent material;
- adhering the first and second imaging bodies to each other in an overlapping relationship;
- and
- adhering the first and second imaging bodies to a marker substrate.
