Plane-wave (PW) ultrasound imaging allows for ultrafast image acquisition rates, thus enabling new biomedical applications, such as ultrasound-based blood flow and tissue motion characterization. We propose two novel Fourier domain techniques for PW ultrasound image reconstruction that can be used as an alternative to conventional delay-and-sum beamforming. In particular, we show how to modify two classic algorithms used for geophysical data processing (namely, Stolt's and slant-stack depth migration under zero-offset constant-velocity assumptions), so that their new versions can be used for PW ultrasound data processing. To demonstrate the merits and limitations of our approach, we provide qualitative and quantitative comparisons with other Fourier domain methods reported in the ultrasound literature. Our evaluation results are based on the image resolution, contrast, and similarity metrics obtained for several public-domain experimental benchmark data sets.
平面波（PW）超声成像是实现超快速图像采集率的一种手段，因此能够实现新的生物医学应用，如基于超声的血流和组织运动特征描述。我们提出了两种用于 PW 超声图像重建的新的傅里叶域技术，可作为传统的延迟求和波束形成的替代方法。特别地，我们展示了如何修改用于地球物理数据处理的两个经典算法（即，Stolt 偏移距为零的常规速度假设下的倾斜叠加深度偏移和），以便可以将它们的新版本用于 PW 超声数据处理。为了展示我们的方法的优点和局限性，我们与超声文献中报道的其他傅里叶域方法进行了定性和定量比较。我们的评估结果基于对几个公共域实验基准数据集获得的图像分辨率、对比度和相似性指标。
