WAVELET PACKET TRANSFORM IN RAW ULTRASOUND SIGNAL PROCESSING

Radim Kolář - Jiří Kozumplík

   A new modification of incoherent processing (IP) method for speckle reduction in ultrasound (US) images has been developed. This method combines filtering of the radiofrequency (RF) signal with the wavelet packet filters and envelope averaging to enhance classical incoherent methods. The comparison with standard IP method is made.
