RESUMEN

Se presenta un método para el procesamiento de señales en aplicaciones médicas que utilizan técnicas de diagnóstico basadas en ultrasonido Doppler. El método está orientado a obtener una mejor representación de la señal de flujo sanguíneo, a partir de la identificación y exclusión de los ciclos, de dicha señal, que se encuentran afectados por distorsiones eventuales. Esto permite, de manera robusta y confiable, estimar parámetros y extraer información clínicamente útil con el objetivo de formular diagnósticos precisos sobre la funcionalidad del objeto examinado. Se muestran los resultados de la aplicación del método sobre señales reales de flujo sanguíneo obtenidas durante procedimientos de revascularización coronaria y se demuestra que la estimación de los índices clínicos de interés mejora considerablemente cuando los ciclos detectados como afectados por ruido eventual son excluidos del análisis.
