Automated Estimation of Acute Infarct Volume from Noncontrast Head CT Using Image Intensity Inhomogeneity Correction

Figure 2

Simulated MCA territory infarcts. The figure illustrates the visual appearance of simulated MCA-territory infarcts of various (known) attenuations (top) and the appearance of each known attenuation on the difference map (bottom). The simulated territory is shown top-left for reference. Infarcts of less than 20% decreased density show poor margin delineation.
