Tissue mimicking phantom images formed using (a) DAS, (b) ADMIRE, (c) DAS+CF and (d) ADMIRE+CF. The dynamic range is 60 dB. The DAS image in (a) also shows two enclosed areas by white dashed lines and a circle by white solid line (i.e., mask regions) that were used to quantify contrast, contrast-to-noise ratio (CNR) and speckle signal-to-noise ratio (SNRspeckle) for each imaging data. An ‘L’ or ‘B’ denotes lesion or background, respectively.
