The idea of this research is to design a program to analyze Ischemic Stroke Area, comparing image data from CT scanned images of CBV, CBF and MTT which were collected from CT Perfusion, which rely on the relationship of all three scattered data to identify Ischemic Stroke Area based on data gathered from Mismatch of CBV, CBF images and calculate the Threshold of MTT for preliminary data analysis for the doctors which is easy to use and at cheap price, also to reduce the time for doctor to analyze the case and increase the accuracy of analysis for effective treatment.
