Abstract :
A computationally efficient, easily implemented, and highly effective algorithm is developed to remove burst noise due to radiofrequency pulses used in functional magnetic resonance imaging (FMRI) from concurrent physiologic time series. The algorithm is used in this case to eliminate FMRI burst noise from electrocardiograms, but may also be employed in any situation where nonlinear manifestations of measurable noise instantaneously corrupt a desired signal
