Amyloid deposition is associated with impaired default network function in older persons without dementia (2009, methodology): “Functional data were realigned using INRIAlign, a motion correction algorithm unbiased by local signal changes (Freire and Mangin, 2001).”
Mutual-information-based registration of medical images: a survey (2003, methodology): “[14], [24], [26]–[30], [32], [35]–[37], [41]–[44], [47], [49]–[53], [57], [64], [67], [69]–[71], [76], [80], [84], [86], [88], [92]–[94], [97]–[101], [104], [107] [108], [111], [115]–[117] [123], [125], [126], [135], [136], [140]–[142], [150], [160], [162].”
Visually guided grasping produces fMRI activation in dorsal but not ventral stream brain areas (2003, background): “No head motion artifacts were observed, likely because our subjects were highly experienced, so no motion correction was applied (Freire and Mangin 2001).”
Influence of heart rate on the BOLD signal: the cardiac response function (2008, methodology): “Coregistration, however, was not performed since (1) motion was expected to be minimal because a bite-bar was used, (2) coregistration causes unintended smoothing across voxels, which would interfere with our voxel-wise analysis, and (3) estimation of coregistration parameters can be biased by activ”
What is the best similarity measure for motion correction in fMRI time series? (2002, methodology): “of the Gaussian kernel used to spatially smooth the data before registration in order to reduce the number of local minima [8].”
Dysfunctional action monitoring hyperactivates frontal-striatal circuits in obsessive-compulsive disorder: an event-related fMRI study (2005, unknown): “Two functional image runs were realigned using INRIAlign, a motion correction algorithm unbiased by local signal changes (Freire and Mangin, 2001; Freire et al., 2002).”
Estimating the number of independent components for functional magnetic resonance imaging data (2007, methodology): “Images were realigned using INRIalign—a motion correction algorithm unbiased by the local signal changes (Freire et al., 2001; Freire and Mangin, 2001).”
