Abstract

UN SISTEMA ELECTRONICO (1) PARA MEDIR LA DENSIDAD Y ESTRUCTURA DE UN HUESO, EN EL QUE UNA UNIDAD CENTRAL ELECTRONICA (3) ESTA EQUIPADA CON CALIBRES ULTRASONICOS (5) DISEÑADOS PARA APLICARSE A UN SEGMENTO DEL CUERPO HUMANO (POR EJEMPLO UN DEDO) QUE CONTIENE TEJIDO OSEO PARA SER EXAMINADO. LA UNIDAD CENTRAL (3) ESTA DISEÑADA PARA MOSTRAR EN UNA PANTALLA (17) UNA IMAGEN (S) DE LA SEÑAL ULTRASONICA EMITIDA A TRAVES DEL TEJIDO OSEO Y SUBRAYAR SOBRE LA IMAGEN (S) DOS LINEAS MARCADORAS VERTICALES (RTO,RTM) CORRELACIONADAS CON LA VELOCIDAD CON LA QUE LAS SEÑALES ULTRASONICAS SE TRANSMITEN A TRAVES DEL TEJIDO OSEO Y LA VELOCIDAD DE TRANSMISION DE LAS SEÑALES ULTRASONICAS A TRAVES DE TEJIDO BLANDO. ESTAS LINEAS MARCADORAS VERTICALES (RTO,RTM) TRAZAN LA PORCION DE LA IMAGEN QUE REPRESENTA LA SEÑAL ULTRASONICA RECIBIDA TRAS PASAR A TRAVES DEL TEJIDO OSEO. LA AMPLITUD DE ESTA SEÑAL DEPENDE DE LA ABSORCION DE ULTRASONIDO CUANDO PASA A TRAVES DEL TEJIDO OSEO.
