Segmentation of Hyperacute Cerebral Infarcts Based on Sparse Representation of Diffusion Weighted Imaging

Figure 10

An axial slice of a patient with inhomogeneous infarcts involving the cortex, the DWI (a), ADC (b), ground truth infarcts (c), segmented infarcts by the proposed method (d), the FCM method (e), the FCM_ROI method (f), the DM method (g), and the DM_ROI method (h). Red arrows point to false positive regions, which could be eliminated by ROI confinement.
