2D focusing results for standard and improved DAS
algorithms, for different horizontal planes along the -axis: (a) standard DAS
, (b) standard DAS , (c) standard DAS , (d) improved DAS
, (e) improved DAS , (f) improved DAS . 2D contour plots
show signal energy on a linear scale, normalised to the maximum in the 3D
volume; values below 0.1 are rendered as white.
