We introduce methods and hardware for rejection of high levels of interference from MR data, allowing the acquisition of MR imaging scans outside the shielded room and with no disruption to patient care. Interference cancellation relies on deriving a transfer function between “primary” sensors that detect MR signal and interference, and “reference” sensors that detect interference only. Interference rejection up to 67 dB is demonstrated, along with imaging results from scans acquired at the patient bedside in a Neuro ICU.
