If your MRI setup has a
fi
lter plate separating the control room and MRI room, the
fi
lter plate may have additional
RF
fi
ltering. Sometimes the
fi
lter plate may slightly increase noise in the image. In that case, use a waveguide if
available and the TDT RF
fi
lter.
If the distance from the scanner room to the control room is >5 meters (e.g. vertical bore magnets such as the
Brukner 9.4 T) it may be necessary to leave the PZ5 / PZA in the MRI room. In that case the further the PZ is from
the peak gradient lines the longer the battery life. We recommend that the guass
fi
eld be less than 50 guass
