A Novel Ultrasonic Image Zooming Algorithm Based On Sparse Representation

In ultrasound imaging, it is usually needed to zoom in the B-mode image with high resolution. Therefore, a novel ultrasound image super-resolution zooming algorithm based on sparse representation was introduced in this paper. Sparse representation can achieve super-resolution reconstruction as long as the signal is sparse in certain dictionary. Simulation results show that our method outperforms the other methods not only on visual perception but also on edge protection.
