Coherent plane wave compound imaging has already shown to provide equal image quality as multi-focal conventional imaging at more than ten times higher frame rates. Furthermore, image reconstruction of plane wave ultrasound is more computational efficient in Fourier domain (e.g. Lu's or Stolt's f-k) than in spatial domain (e.g. Delay-and-Sum (DAS)). In this study we fully integrated the Stolt's f-k method and coherent compounding in the Fourier domain to further increase its computational efficiency. Additionally, we introduced a weighting template for Fourier domain methods which is rotated as a function of plane wave transmission angle (angular weighting) and investigated how it affects contrast and resolution of coherently compounded images.
