• Uses two microcoils to track catheter position and orientation
• Monitors position of target tissue to automatically create a slice plane containing two microcoils and target tissue
• 0.2 T open-MRI with single receive channel
  • Uses a 'detuning' coil to select signal from either microcoil 1 or 2 (needed b/c of single 'receive' channel of MR)
• Talks about cancelling 'resonance offset conditions' by using an average position from opposite-poarity readout gradient
• True-FISP or PSIF sequences
