Time frequency analysis of ultrasound doppler signal by s-transform and wigner-ville distribution

Mahieddine Latfaoui, Fethi Bereksi Reguig

Abstract


Ultrasound Doppler signal processing is a necessity in several disciplines of medicine. The interpretation of these signals allows a good diagnosis of patients in order to detect certain diseases. In this work, we will use different non-parametric time-frequency techniques such as the Wigner-Ville distribution (WVD), the Pseudo-Wigner-Ville distribution (PWVD), the smoothed pseudo Wigner-Ville distribution (SPWVD), and the S-transform in order to analyze the Ultrasonic Doppler signal of the femoral arteries.


Keywords


Ultrasound Doppler signal, S-transform, Wigner-Ville distribution, Pseudo-Wigner-Ville distribution, and smoothed pseudo Wigner-Ville distribution.
