Abstract :
In ultrasound strain imaging, random fluctuations of the signal amplitude result in a match only occurred at certain regions from pre- and post-compression window pairs. This produces amplitude modulation (AM) strain noise. In this paper a new suppressing amplitude modulation method called displacement filed correction (DFC) is presented. Both simulation and phantom experiment demonstrate that the presented method can efficiently reduce amplitude modulated strain noise and achieve the considerable improvement in the strain image quality and performance.
