Adaptive Sparse Representation Beamformer for High-Frame-Rate Ultrasound Imaging Instrument.

To overcome the disadvantages of low signal-to-noise ratio (SNR) and poor resolution and maintain the high frame rate in plane wave (PW) emission, a novel adaptive sparse representation beamformer (SRBF) for PW emission is proposed. Signal sparse representation with an overcomplete basis can accurately distinguish correlated or even coherent broadband signals coming from different positions in a s...
