Figure 1.3: Brain MRI representation. The first row illustrates the 3D volume and its3 different orientations (axial, coronal, and sagital respectively from left to right)
Figure 2.2: Head MRI representation. The three orientations are ilustrated: (a) axial, (b)sagital, and (c) coronal
Figure 2.3: MRI intensity corrections. First row represents a BrainWeb T1w simulatedimage: (a) original image, (b) 9% of noise image, (c) 40% of bias field image, and (d)image with both effects applied
Figure 2.5: Brain tissue segmentations: (a) Average atlas and its prior tissue maps ((b)WM, (c) GM and (d) CSF) used in SPM12 for tissue segmentation.The second rowrepresents (e) the original T1w 3T MRI data and the tissue mask results in red: (f) WM,(g) GM and (h) CSF.
