Özet

In this study, correlation dimension analysis was performed on the Doppler signals taken from healthy, mild and serious degree stenosed carotid artery. Correlation dimension is the number of a dynamic system's freedom degrees and is a indicator of the system complexity. Correlation dimension have computed on 8 embedding dimension using the time delay value determined through mutual information function for each Doppler signal. t-test has been performed and a statistically significant difference (p < 0.0001) was obtained.
