filter out unwanted
information from the images, such as numbers, letters etc.,
and then take CBV , CBF and MTT images into IdentifY
Area process to pull out the part we want to compare. Then
take the interested color (RGB) from the CBV , CBF and
MTT images to make comparison (Grey Scale) in order to
determine the relationship from table 1 to gather D-Match,
Mismatch, N-Match and Undefined area then specify the
area of the brain into two part to identify Ischemic Stroke
Area (Left/Right Brain), such progress is shown in Fig. 3 .
