Figure 2

Intrasubject data normalization brings intersubject data distribution close to a normal distribution. The left figure (a) shows absolute values of Hbt; and the right figure (b) shows the population distribution of zHbt after intrasubject normalization [see Eq. 1 and note that each subject is normalized individually]. Each trace represents the healthy region of one subject. For clarity of presentation, the vertical axis is normalized to the total number of voxels in each subject.
