Average spectra through depth and across subjects are shown for (a) three beamforming methods, SPW (teal), PWSF (orange), and MPW (purple), before (thick) and after (thin) adaptive demodulation for the data acquired with the L12-5 probe (7.8MHz imaging frequency, imaging cases 1–3) and (b) the SPW beamforming method before (thick) and after (thin) adaptive demodulation for the data acquired with the C5-2 probe (3.1MHz imaging frequency, imaging case 4). A 35 sample median filter was used for the adaptive demodulation for both cases.
