Historia del diagnóstico por ultrasonido: Aplicaciones en el Hospital San Juan de Dios
Keywords:
diagnóstico por ultrasonido, Historia (es)Downloads
La acústica como ciencia es muy antigua. Trabajos de Pitágoras muestran la relación existente entre la longitud de las cuerdas vibrantes y el sonido percibido. En 1624 Descartes y Snell enuncian las leyes de la refracción de las ondas. Christian Huyghens, en 1690, concluyó que los puntos alcanzados por una perturbación pueden considerarse como otras tantas fuentes secundarias. Este es el enunciado de uno de los principios básicos de las teorías ondulatorias.
