摘要： A radio frequency receive coil (50) includes an antenna (52, 52') that is tuned to a magnetic resonance frequency to detect a magnetic resonance signal. Electronics (54) disposed on or with the antenna (52, 52') as a unitary structure include compression circuitry (102, 114, 202, 214, 230, 330, 430, 530) that compresses the magnetic resonance signal at a gain controlled by a gain control signal to produce a compressed magnetic resonance signal. The electronics (54) generate a reduced dynamic range representation of the magnetic resonance signal based on the compressed magnetic resonance signal. The reduced dynamic range representation of the magnetic resonance signal is communicated off the receive coil.

摘要： 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.

摘要： An active position marker system comprising at least one active position marker (10) and a remote transceiver unit (20) for communicating with the position marker is disclosed. Basically, the position marker (10) comprises a local RF receive coil (11) for receiving MR signals which are excited in a local volume, and a parametric amplifier (14) for amplifying and upconverting the frequency of the received MR signal into at least one microwave sideband frequency signal. This microwave signal is transmitted wirelessly or wire-bound to the transceiver unit for downconverting the same and supplying it to an image processing unit of an MR imaging apparatus.
