First Claim
1. An integrated skin-mountable multifunction device for use with an image guided surgical system, the device comprising:
- a plurality of layers, each layer performing one or more specific functions, including;
a first layer that includes a patient mountable surface;
a second layer that includes at least one position indicating element;
at least one imageable pattern whose geometry is known in a coordinate system of the at least one position indicating element, wherein the imageable pattern is visible on an imaging modality; and
a cover layer, wherein each of the plurality of layers are removable from one another and wherein the device is configured to accept one or more additional layers for performing additional functions between the first layer and the cover layer, wherein the second layer comprises a circuit board having the at least one position indicating element mounted thereon and wherein the imageable pattern is etched on the circuit board.
