A Novel Approach to Tele-Ultrasound Imaging: Compressive Beamforming in Fourier Domain for Ultrafast Ultrasound Imaging

Tele-ultrasound imaging is useful in various situations. Plane wave provides a method for ultrafast ultrasound with very high frame rates, which sacrifices image quality and leads to the problem of large amount data low signal transmission speed telemedicine imaging. In this paper, novel compressive frequency-wavenumber domain beamforming introduced, integrates Stolt’s f-k compressed sensing theory on lateral wavenumber. The load reduced by sparsity echo parallel transducer, requires smaller measurement matrix during reduce memory usage accelerate rate. Fourier obtain greater stability better after reconstruction than if it was temporal domain. Simulated experimental acquisitions were used compare conventional delay-and-sum (DAS) beamforming. results showed that within wavenumber higher from less data.
