Abstract

Método y su correspondiente instrumento utilizando ultrasonidos con haz orientado para medir la velocidad de circulación de la sangre y líquidos similares, caracterizado el instrumento porque incluye un conjunto de transductores provisto de una pluralidad de elementos transductores electroacústicos para transmitir impulsos de ultrasonido con una frecuencia de emisión predeterminada y para generar señales de eco recibidas, un dispositivo transmisor para excitar secuencialmente unos elementos transductores elegidos con una programación en el tiempo de elemento a elemento con el fin de generar un impulso ultrasonoro de banda estrecha que se propaga a lo largo de una línea de exploración radial elegida y que se aplica a un volumen de muestra del objeto sometido al exámen a través del cual se está midiendo la velocidad de circulación hacia y a partir del conjunto, un dispositivo receptor de canales múltiples para demodular coherentemente dichas señales de eco con referencias de frecuencia de emisión en cuadratura de fase y para retardar en el tiempo y sumar las señales en fase y una señal focalizada en cuadratura, una puerta de alcance para extraer un par de muestras analógicas en paralelo a partir de dichas señales focalizadas en fase y en cuadratura después de cada transmisión de impulso en un momento que corresponde a la recepción de los ecos retrodispersos a partir del volumen de muestra, un procesador digital complejo de transformada de Fourier para derivar repetidamente a partir de grupos de dichos pares de muestras analógicas la magnitud y el signo de la variación de frecuencia de los ecos respecto a la frecuencia de emisión y por tanto la velocidad y la dirección de circulación, y un dispositivo de visualización para representar visualmente la velocidad bidireccional en función del tiempo.
