Patent ID: 8644906

Claim:
A method for identifying a physical location on a body surface of a patient, the method comprising: providing a patch including: a flexible base layer that is mountable on and substantially conformable to a patient's body surface, the base layer having opposed upper and lower primary surfaces; a flexible substrate that is releasably attached to the upper primary surface of the base layer and substantially conformable to the patient's body surface; and at least one MRI-visible fiducial element defined by or secured to the flexible substrate; securing the base layer to the body surface to mount the patch on the body surface such that the flexible substrate conforms to the body surface; thereafter MRI scanning the patient with the patch on the body surface to generate corresponding image data; thereafter identifying a physical location on the body surface using the image data; and removing at least a portion of the flexible substrate, including the at least one fiducial element, from the base layer, wherein the base layer remains secured to the body surface when the at least a portion of the flexible substrate is removed from the base layer.
