Parallel implementation of a Choi-Williams TFD for Doppler signal analysis
The spectral width and mean frequency of Doppler signals is used to measure and characterise lesion-induced flow disturbance. Conventional methods of spectral estimation based on the Fourier Transform compromise the measurement accuracy since these methods implicitly assume signal stationarity durin...
