A Post-Beamforming 2-D Pseudoinverse Filter for Coarsely Sampled Ultrasound Arrays
Beamforming artifacts due to coarse discretization of imaging apertures represent a significant barrier against the use of array probes in high-frequency applications. Nyquist sampling of array apertures dictates center-to-center spacing of λ/2 for elimination of grating lobes in the array pattern....
