Fig. 1From: Partial volume correction for arterial spin labeling using the inherent perfusion information of multiple measurementsGM CBF maps (middle slice) estimated using different correction methods under different noise levels. From left to right: no correction, LR, sEM, and sEM-LR methods. From top to bottom: different levels of Gaussian noise, with a standard deviation of 5, 10 and 15, respectively. The dotted box areas of ground truth and the corrected results with LR, sEM and sEM-LR were magnified into viewBack to article page
