Abstract
The device of the present application is an adhesive surface marker comprising a gel sealed by a casing and membrane structure. The markers of the present invention can include a cavity for receiving imaging materials. The markers provide 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, retain their shape and size, and do not suffer from water-loss which can lead to reduced density to certain radio-graphic modalities (e.g. MRI).
