... in the implementation of inverse filtering scheme. The SST is also applied to estimate the quality factor using the peak frequency shift method. Therefore, we propose a completely efficient work flow to estimate and compensate attenuation using the SST. Synthetic examples and real data demonstrate the robustness...
