Abstract: Stroke is the 4th leading cause of death in the US, with one person dying every 4 minutes as a result. Approximately 800,000 people have a stroke each year; about one every 4 seconds. Strokes occur due to problems with the blood supply to the brain; either the blood supply is blocked or a blood vessel within the brain ruptures. Due to the increase in misdiagnosis in medical for example misdiagnosis of stroke in brain. This Led to make correct medical diagnosis through many ways. However, it is not easy to correctly diagnose the stroke. In this paper our aim to present a foundational approach to assisting physicians when making medical diagnose for brain stroke. Brain stroke has been detected using image segmentation. The researcher use Matlab image processing software to analyze brain stroke image captured from magnetic resonance imaging (MRI).
