On de-cluttering and de-noising ultrasound images with Time-domain Compressive Beamforming

Time-domain Compressive Beamforming (t-CBF) uses a beamforming matrix in conjunction with regularization techniques to improve the image quality in single-insonification ultrasound acquisitions. It was originally introduced as a way to reconstruct sparse images of point scatterers in a homogeneous medium. Later on, it was adapted to tissue imaging using the wavelet transform to sparsify the reconstruction.
