A Fuzzy clustering method was developed for a multi-functional correlation map generated from the cerebral functional images with positron emission tomography (PET) and was evaluated for a patient with internal carotidartery occlusion studied pre- and post- operation. The multi-functional correlation map of cerebral blood flow measured with 15O labeled water at resting, hyper ventilation (HV) and Acetazoramide loading (AZ) states, was clustered into two (normal and diseased) groups by the Fuzzy clustering method. Classified regions of normal and disease were almost same as the regions clustered by a hierarchical clustering method. The recovered region, which was normal CBF and moved low to normal response to AZ loading and HV by operation, was depicted in the post-operative clustered images. This clustering method is considered to be available to represent simply the complex functions of the brain.
