The manuscript of this thesis is divided into four chapters. In the first chapter, a brief summary of the applications of ultrasound imaging is given as well as its benefits. The problem that this work addresses is indicated and the objectives of the thesis are formulated. A short summary of the manuscript is also provided. In the second chapter, the theoretical context of acoustic wave propagation is fixed. In addition, based on this formulation, conventional ultrasound acquisition schemes are reviewed and the usual metrics that quantify the quality of the image are introduced. We also summarize the already existing approaches to overcome the trade-off between image quality and frame rate. Chapters three, four and five present the most imp...
