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

Figure 5

From (a) to (c), an axial slice of DWI and ADC and the corresponding ROIs for detecting infarction overlaid in color on the DWI, where regions in red are initial ROIs modified from [22] while those in yellow are from morphological dilation.
