Abstract

The device of the present application, an adhesive disk, relates to non-invasive multi-modality radiographic surface markers and provides means for marking patients and diagnostic images taken of those patients through different methods including X-Ray, Computerized Tomography, Positron Emission Tomograph, and Nuclear Magnetic Resonance Imaging among others. The device of the present application also provides means for enabling the accurate location of internal structures of a patient.

Claims

1. A radiographic surface marker comprising

a gel material visible to multiple radiographic imaging methods, said gel material comprising multiple layers of said gel material laminated together forming a first surface and a second surface,

said layers of said gel materials having an aperture therethrough forming first and second openings,

a membrane on said first surface of said gel material and sealing said first opening,

a disk on said second surface of said gel material and sealing said second opening to form a chamber, and

a porous material contained in said chamber.

2. A radiographic surface marker comprising

a gel material visible to multiple radiographic imaging methods, said gel material comprising multiple layers of said gel material laminated together forming a first surface and a second surface,

said layers of said gel material having an aperture therethrough,

a first membrane on said first surface of said gel material,

a second membrane on said second surface of said gel material and,

a plate on said second membrane, said plate having a perforation for alignment with said aperture and having slots for attaching said marker to a tape for removably attaching said marker to a patient.

3. The radiographic surface marker of claim 2 further including the tape to which the marker is attached wherein the tape includes printed marks thereon.
