Abstract

METODO PARA MEDIR LA ATENUACION DE ULTRASONIDOS, ESPECIALMENTE APLICABLE AL CUERPO HUMANO. CONSISTE EN INTRODUCIR IMPULSOS DE ENERGIA DE ULTRASONIDOS, DETECTAR SEÑALES DE BANDA ESTRECHA, ACUMULAR UN PRIMER CONJUNTO ESTADISTICAMENTE INDEPENDIENTE DE DICHAS SEÑALES PRODUCIDAS POR UNA PRIMERA SUPERFICIE (D T 1), ACUMULAR UN SEGUNDO CONJUNTO, SIMILAR AL ANTERIOR, PRODUCIDO POR UNA SEGUNDA SUPERFICIE (D T 2), SEPARADO DE LA PRIMERA SUPERFICIE UNA DISTANCIA DETERMINADA (D) Y CALCULAR LA CARACTERISTICA DE ATENUACION.
