Background, Motivation and Objective In recent years coherent plane-wave imaging (CPWI) has become one of the most popular methods in ultrasound beamforming as it provides equivalent resolution to optimal multifocus imaging using a reduced number of plane wave transmissions (N). It has been described in the literature that the decimation of the angle sequence results on the introduction of grating lobes and the reduction of the contrast ratio (CR). The effect of edge waves is however less documented. Edge waves result on a ghost artifact that lags behind the point spread function (PSF) and impacts both the images CR and axial resolution.
