ABSTRACT
This paper aims to implement a method for signals processing in biomedical applications based on Doppler
ultrasound techniques. The method is aimed to obtain a better representation of the blood flow signal, and it is
based on the detection and exclusion of signal cycles detected as affected by eventual noise. This allows, in robust
and reliable way, to estimate parameters and extract useful clinical information, in order to make accurate diagnoses
on the functionality of the scanned object. The results of applying the method to two blood flow signals in coronary
implants are presented, and it is observed that the estimation of the clinical indices improve when affected cycles are
excluded of the signal analysis.
