[Noise and speckle reduction in ultrasound Doppler blood flow spectrograms by using MP-PCNN].

Abstract

To reduce background noise and Dopplar speckle in the spectrogram of ultrasound Doppler blood flow signals, a novel method, called Matching Pursuit with threshold decaying pulse coupled neural network (MP-PCNN), has been proposed. The proposed method used an iterative algorithm, which decomposed the ultrasound Doppler signals into linear expansion of atoms… (More)
