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 rep

Compressive sensing based on wavelet is applied to ultrasonic medical image. Structured random measurement matrix (SRM) is chosen as measurement matrices to reduce computation. The image is sparsely represented in the wavelet transform space. Finally

Plane wave (PW) emission has the potential advantages of reducing the size of high-voltage pulse-generating circuits and achieving high-frame-rate (HFR) in ultrasound instrument. However, because of the unfocused beams, the signal-noise ratio (SNR) a
