The performance of a low field Point of Care (POC) MRI system operating outside an RF shielded room is adversely affected by the presence of electromagnetic interference signals, which produce image artifacts, sometimes complicated enough to be confused with image noise. We demonstrate a post-processing interference suppression technique using an external reference coil and dynamically updated transfer function to detect the interference and remove it from the imaging data.
