Comparison of physiological noise at 1.5 T, 3 T and 7 T and optimization of fMRI acquisition parameters
…, CJ Wiggins, A Potthast, GC Wiggins, LL Wald - Neuroimage, 2005 - Elsevier
Previous studies have shown that under some conditions, noise fluctuations in an fMRI time-course
are dominated by physiological modulations of the image intensity with secondary …
