Sparsity-driven sparse-aperture ultrasound imaging [PDF]

, 2006
We propose an image formation algorithm for ultrasound imaging based on sparsity-driven regularization functionals. We consider data collected by synthetic transducer arrays, with the primary motivating application being nondestructive evaluation.
