摘要： In a method for imaging a body part of a patient particularly in relation to DBS where conductive elements can reduce a safe SAR level, the power in the RF pulses being delivered to the RF transmit coil is measured in real time by a unit associated with the FR transmit coil and is used to stop the supply of RF pulses to the RF coil in the event that the power exceeds a predetermined safe limit. As signal can also be transmitted to the MR control unit to shut off the imaging sequence.

摘要： In MR imaging in a suite of rooms including a diagnostic room and a second surgical room, the magnet includes a diagnostic table separable from a docking station of the magnet and the second room includes a second surgical table. An imaging control computer controls operation of the imaging system and a movement control computer controls operation of the magnet moving system and the patient support table. During imaging in the surgical room, the diagnostic table is separated and docked at a secondary docking station while an emulating computer system cooperate with the imaging control computer system by emulating outputs from the disconnected diagnostic table for controlling operation of the imaging system.

摘要： The receive coil arrangement includes an inner local volume coil adjacent the part to be imaged so as to maximize the received MR signal and an outer coil, which may be the built in body coil of the magnet, connected by cable to the signal processing system. Both the coils are individually tuned to the common resonant frequency and the local volume coil include an arrangement to halt current flow therein during the transmit stage. The local volume coil has no cable and is arranged to communicate the MR signal therein to the signal processing system through the outer coil by inductive coupling to the outer coil. Despite inherent losses by interfering with the tuning of the loops and in the inductive coupling this magnifies the MR signal and makes the local volume coil wireless.
