Abstract
A noise abatement system includes a processor configured to measure noise in an imaging system and generate a switch mode power supply (SMPS) input signal based on the measured noise and an adjustable switched mode power supply configured to receive the SMPS input signal and adjust a switching frequency of the switched mode power supply, based on the SMPS signal, to operate at a frequency that generates harmonics that are outside of an imaging bandwidth of the imaging system. A system and calibration method are also described herein.
