Stroke is a major cause of death and disability in both the more developed and the less developed world. The core of the lesion that is dead shows up in dwi image as hyper intense region. Previous methods for infarct segmentation from DWI images had many false positives, as they did not use the complementary information from apparent diffusion coefficient (ADC) maps available with DWI images. In the present work, we have combined the contrast information provided by DWI and physiological information provided by the apparent diffusion coefficient (ADC) maps to segment the infarct core automatically.
