Embodiments of the present disclosure provide devices and systems that support wireless communication between wireless communication devices residing within, and external to, a Faraday cage. In some embodiments, devices and systems are provided for transmitting wireless signals through a waveguide port of a Faraday cage for wireless signals having frequencies below the cutoff frequency of the waveguide port, where a portion of the waveguide port is compromised by the presence of a conductor, thereby permitting the propagation of electromagnetic waves. In some embodiments, aspects of the present disclosure are employed to adapt a magnetic resonance imaging system for communications between a scanner room and a control room.

Systems, devices and methods for transmitting electrical signals through a Faraday cage

A method for automatically measuring currents induced on conducting structures positioned in the bore of a magnetic resonance imaging ('MRI') scanner using a single magnetic resonance image is provided. A conductive structure is positioned within the bore of the MRI scanner during imaging. When the MRI system is transmitting an RF field, a current is induced in the conductive structure. The current creates a magnetic field at the Larmor frequency, which couples to the RF magnetic field in the vicinity of the conductive structure. The modified magnetic field results in an artifact being generated in phase images. The artifact in the phase image is then analyzed to determine the current induced in the conductive structure.
