Simulación y análisis del comportamiento de microburbujas empleadas como ecopotenciadores en la sangre

Microbubbles are used as contrast media for ultrasound and their oscillations can be described under various models. At present, microbubbles are highly used as ultrasonic contrasts, to better explore cavities that cannot be detected with the naked eye by the ultrasound technique. Chapter 1 gives a brief introduction to the models to be used, the objectives and the background. In Chapter 2, the equations that model the behavior of the microbubbles of the linear and non-linear model are presented in detail, evaluating the mathematical models that represent their behavior when they are subjected to an acoustic field. In Chapter 3 results are obtained from the implementation of a simulation capable of recreating the behavior of a microbubble under the effects of ultrasonic waves and its subsequent coupling in both the linear and non-linear models. In chapter 4 the results obtained from the simulations of the linear and non-linear models for a single bubble and its subsequent coupling with several bubbles are exposed. Finally in chapter 5 the conclusions reached from the results obtained are detailed. The characteristics of the microbubbles are analyzed in order to understand the dynamics of these when they are used as eco-enhancers, the results obtained contemplate a uniform relationship with the linear and non-linear models; because the size of the bubble and the separation that exists between bubbles is always homogeneous; Despite this, it is a starting point for a future analysis where these characteristics may vary
