Development of a MATLAB Environment Software for Simulation of Ultrasonic Field.
The study of the acoustic field generated by an ultrasonic transducer is fundamental to its construction and characterization, because it defines how it will behave before being built. It also defines whether it is feasible or not, for the application to which it was designed. It can also lead to mo...

It also defines whether it is feasible or not, for the application to which it was designed. It can also lead to modifications to the project so it behaves as expected. In this work, a software was implemented in MATLAB®, for computational simulation of acoustic fields generated by ultrasonic transducers of different configurations. Two models were used, Zemanek and Stepanishen. Transducers with focus and apodization and transmission medium with attenuation may also be simulated. For the simulation of Zemanek's model, the mathematical method of discretization was used. The Stepanishen's model used an analytical solution for the impulse response. The developed programs were aggregated into a computer package, named FSIM, and a graphic interface was created. The user can choose among some of the transducer configurations and simulation parameters already implemented. FSIM has a modular architecture and allows further simulation modules to be added. The simulations were validated comparing results to those previously published in classical papers from Zemanek, and from Lockwood and Willete, in addition to prior results from research studies conducted at the Biomedical Engineering Department of the School of Electrical and Computing Engineering at the Universidade Estadual de Campinas (UNICAMP). El estudio del campo acústico generado por un transductor ultrasónico es fundamental para su construcción y caracterización, ya que define cómo se comportará antes de ser construido. También define si realmente es factible para la aplicación a la que fue diseñado, y también puede sugerir modificaciones al proyecto, para que se comporte como se espera. En este trabajo un software fue implementado en MATLAB®, para la simulación computacional de los campos acústicos generados por los transductores ultrasónicos de diferentes configuraciones. Dos modelos fueran usados, Zemanek y Stepanishen. Transductores con el enfoque y apodización y medios con atenuación también pueden ser simulados. Para la simulación del modelo de Zemanek, se utilizó el método matemático de discretización y para el modelo de Stepanishen, se empleó una solución analítica para la respuesta impulsiva. Los programas desarrollados fueron agregados en un paquete computacional, llamado FSIM, y una interfaz gráfica fue creada. El usuario puede elegir entre algunas configuraciones del transductor y parámetros de simulación ya implementados; FSIM tiene una arquitectura modular y permite que otros módulos de simulación sean añadidos. Las simulaciones fueron validadas comparando resultados obtenidos previamente por otros trabajos de investigación del Departamento de Ingeniería Biomédica de la Facultad de Ingeniería Eléctrica y Computación de la UNICAMP y por los artículos clásicos de Zemanek y Lockwood y Willette. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y custom: Copyright of Biomedical Engineering Journal / Revista Ingeniería Biomédica is the property of Biomedical Engineering Journal / Revista Ingenieria Biomedica and its content may not be copied or emailed to multiple sites without the copyright holder's express written permission.
