WebApr 7, 2014 · Head motion has long been known as a confounding factor in brain imaging including MRI ( 1, 2 ), PET ( 3, 4 ), single-photon emission computerized tomography ( 5, 6 ), and near infrared spectroscopy ( 7 ), but has raised particular concerns recently following the growing prominence of resting-state functional connectivity MRI. WebFirst, move your head from side to side while looking straight ahead (translation along the x-axis). Then, move your head forward and back (y-axis) and up and down (z-axis). Try the rotations as well. We do the same procedure with our volumes.
