Implantable dielectrometer

A diagnostic method, comprising:

• implanting a dielectrometer probe, comprising first and second conductors, in proximity to a target tissue in a body of a human subject;
• applying a radio-frequency (RF) signal to the probe;
• and
• evaluating, responsively to a signal from the probe, a dielectric property of the target tissue;
• wherein the first and second conductors are arranged to:
• provide a coaxial contact to the target tissue at a distal end of the probe, or
• define a resonant ring in proximity to the target tissue.

A diagnostic method, comprising:

• implanting a dielectrometer probe, comprising first and second conductors, in proximity to a target tissue in a body of a human subject;
• the first and second conductors arranged to define a transmission line in proximity to the target tissue;
• applying a radio-frequency (RF) signal to the probe;
• and
• evaluating, responsively to a signal from the probe, a dielectric property of the target tissue;
• wherein:
• the transmission line is defined by arranging the first conductor as a ground plane and the second conductor as a microstrip parallel to the ground plane;
• or
• the transmission line comprises a coplanar waveguide.
