摘要： A magnetic resonance system includes a wireless power detection sensor and a wireless energy harvesting circuit. The wireless power detection sensor detects magnetic resonance transmissions of the magnetic resonance system. The wireless energy harvesting circuit harvests energy from the magnetic resonance transmissions based on the wireless power detection sensor detecting the magnetic resonance transmissions.

摘要： A balun is provided that is suitable for use with miniature coaxial cables and that obviates the need to cut the cable in order to install the balun. A portion of each coaxial cable that extends from the RF receive coils to the RF receiver is wound multiple times around a device to form an inductor. The inductor may be used with or without a separate resonant circuit. If used with a separate resonant circuit, the inductor and the resonant circuit couple with one another to generate a coupled impedance that provides common-mode noise suppression at the frequency of interest. If used without a separate resonant circuit, the inductor formed in the cable provides an inductance and the capacitance between the windings coupled with the inductance provides a series impedance that suppresses common-mode noise at the frequency of interest.
