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...
Ultrasound elastography has been well applied in medical detection as a tool to aid diagnosis. However, in conventional ultrasound elastograms, there are patterned artifacts from non-white estimation errors. In this paper, we investigate spatial angular compounding methods to reduce the errors. The method involves averaging ultrasound angular elastograms around the same region-of-interest but from...
