2D filter design for the reduction of beamforming artifacts in coarsely-sampled imaging apertures

We have previously introduced a k-space based 2D post-beamforming filter for restoring image contrast loss due to coarse sampling of the imaging apertures. The 2D regularized imaging operator was obtained and implemented on full frame data in k-space using computationally-efficient 2D fast Fourier t...
