Synopsis

Keywords: System Imperfections: Measurement & Correction, System Imperfections: Measurement & Correction, EMI, interference, pilot toneFive devices that are relevant in interventional setting and a Pilot-Tone generator are assessed in terms of their electromagnetic interference with 0.55T MRI. Two of the devices (ergometer and flat-panel television) generated significant interference, however acceptable image quality was achieved when using the EDITER interference cancellation technique. EDITER also enabled the use of higher Pilot-Tone amplitudes and use of cheap, general-purpose signal generator for Pilot-Tone generation.
