WebNov 6, 2013 · By varying, for example, field of view, scan parameters, magnetic field strength and slice thickness, the SNR of MRI images can be increased because these parameters influence the background noise. On the other hand, scanning hardware has also a major influence on the SNR levels of fMRI data. WebField-mapping techniques using a reference scan allow accurate distortion correction of EPI data. However, due to the strong B 0 dependency with head motion and other physiological artefacts in fMRI acquisitions, the reference field-map does not adequately correct for dynamic non-linear changes in image intensity.
