http://www.mrishark.com/aliasing.html WebbIn this article, we review some of the basic principles of imaging, and how metal-induced susceptibility artifacts originate in images. We describe common ways to reduce or modify artifacts using readily available imaging techniques. Next we describe advanced methods to correct readout-direction artifacts and slice-direction artifacts.

WebbImaging artifact is reduced by subtracting an averaged artifact waveform, followed by adaptive noise cancellation to reduce any residual artifact. This method was validated in recordings from five subjects using periodic and continuous fMRI sequences. Spectral analysis revealed differences of only 10 to 18% between EEG recorded in the scanner ...
