Abstract
A medical device enables effective magnetic resonance imaging inside a lumen of a medical device. The medical device includes a plurality of conductive traces formed on a substrate. The conductive traces form an inductive-capacitance circuit or a resistive-inductive-capacitance circuit. The inductive-capacitance circuit or resistive-inductive-capacitance circuit is tuned to a frequency associated with magnetic resonance imaging, an operating frequency associated with a magnetic resonance imaging scanner, a harmonic of an operating frequency associated with a magnetic resonance imaging scanner, or a sub-harmonic of an operating frequency associated with a magnetic resonance imaging scanner.
