1. A method for magnetic resonance imaging, comprising:

  • implanting an implant structure into a body, wherein the implant structure comprises;

    a RF coil, wherein the RF coil detects changing magnetic fields and produces and output RF signal;

    a mechanism for adjusting an impedance of the RF coil so as to select a resonance frequency of the RF coil, wherein the mechanism for adjusting the impedance of the RF coil is capable of receiving input regarding a desired resonance frequency;

    locating an external RF coil external to the body, wherein the external RF coil is inductively coupled to the RF coil;

    exciting a portion of the body proximate the implant structure with RF excitation;

    detecting the output RF signal produced by the RF coil and inductively coupled to the external RF coil.
