1. A method for localizing a tissue region of a patient, comprising:
- a) placing a remote activating device and a patient in proximity to each other,wherein said remote activating device generates a magnetic field, andwherein said patient comprises a tag at a location in, on, or proximal to a tissue of said patient; and
b) localizing said tag in said patient by generating a magnetic field with said remote activating device and detecting a signal from said tag using a detector component,wherein said detector component comprises an electronics component and at least one sense coil and is attached to, or integrated with, a surgical device, wherein said electronics component comprises a signal processor, andwherein said detector component and said remote activating device are separate.
