摘要：

Coherent plane-wave compounding (CPWC) ultrasonography is an important imaging modality that allows for very high frame rates. During CPWC image reconstruction, computationally expensive delay-and-sum beamforming can be replaced by faster Fourier-domain remapping. We show that the cost of such spectral reconstruction can be reduced further, by employing scaled fixed-point arithmetic amenable to efficient beamforming hardware realization.
