Blind Deconvolution for Ultrasound Sequences Using a Noninverse Greedy Algorithm

Table 1

Comparison of different restoration techniques according to 𝑛MSE (𝑛-Mean Square Error) from (10) and RG (resolution gain). RG is a parameter which evaluates the level of decorrelation for speckle noise in the resulted signal.

Methods	SNR = 7 dB		SNR = 14 dB		SNR = 21 dB
