Detection of Doppler Microembolic Signals Using High Order Statistics

Table 1

Training phase results of the optimal thresholds that best maximize the sensitivity and specificity for the standard energy detector and skewness and kurtosis based detectors.

Optimal threshold that maximizes the sensitivity and specificity Sensitivity (%) Specificity (%)

Standard energy detector 5 dB 67% 58%
Skewness detector 76% 91%
Kurtosis detector 77% 91%
