Abstract
An improved magnetic resonance (MR) imaging system (10) is provided. A plurality of receiver coils (12) may be configured to supply respective coil output signals based on a plurality of magnetic resonance response signals sensed by the receiver coils. Each receiver coil defines an enclosure constituting a Faraday cage. At least one circuit device (22) is disposed in the enclosure (24) to condition the coil output signal. This enclosure enables the circuit device (22) to be shielded from electromagnetic interference.
