Strain Image with Spatial Angular Compounding

摘要：

Ultrasound elastography has been well applied inmedical detection as a tool to aid diagnosis. However, inconventional ultrasound elastograms, there are patternedartifacts from non-white estimation errors. In this paper, weinvestigate spatial angular compounding methods to reduce theerrors. The method involves averaging ultrasound angularelastograms around the same region-of-interest but fromdifferent angle views. N decorrelated sub-elastograms areweighted averaged to produce the compounded elastrogram. Forour experiments, we use 3 different angled elastogramscalculated from alternating frames with different steering anglesobtained from base-band data captured by the iMago c21. Wepresent results from a commercial elastic phantom showingimprovement in the elastograms quality parameters such asSNR and CNR.
