Cerebral biopotential analysis system and method |
摘要 |
Disclosed is a real time diagnostic apparatus and method quantitatively evaluating, in a noninvasive manner, cerebral phenomena. Surface electroencephalographic (EEG) signals are obtained and filtered in a desired frequency range. Digital EEG data is normalized and the dynamic phase and density relations within the signal are characterized by processing the filtered signals to generate Kth-ordered spectral values where K is an integer greater than 2. A diagnostic index which quantifies the detected cerebral phenomena is then derived from the generated Kth-order spectral values.
