Abstract

Método para el control en tiempo real del enfoque dinámico en sistemas de imagen ultrasónica y dispositivo calculador de adelanto de muestreo asociado al mismo.#La presente invención divulga un dispositivo y un método que realizan la focalización dinámica en sistemas de imagen ultrasónica, aplicables a inspecciones con presencia de un medio de acoplamiento entre el transductor y la parte inspeccionada. Los sistemas de imagen ultrasónica comprenden un array de N elementos transductores que emiten pulsos ultrasónicos con tiempos de vuelo característicos a puntos focales dentro del objeto a inspeccionar. La presente invención calcula un array virtual equivalente en tiempos de vuelo al array de N elementos, donde cada elemento perteneciente al array de N elementos virtual se calcula a partir de las coordenadas de dos focos F{sub,A} y F{sub,B}, ambos situados en un rayo principal, y de la ecuación: t{sub,K} = t{sub,CF} + t{sub,FA} – t{sub,BF} - t{sub,FV} donde t{sub,CF}, t{sub,FA}, t{sub,BF}, t{sub,FV} son los tiempos de vuelo característicos, y t{sub,K} es una constante independiente de la posición del punto focal.Method for real-time control of the dynamic approach in ultrasonic imaging systems and sampling advance calculating device associated therewith. # The present invention discloses a device and method that performs dynamic focusing on ultrasonic imaging systems, applicable to inspections with the presence of a coupling means between the transducer and the inspected part. Ultrasonic imaging systems comprise an array of N transducer elements that emit ultrasonic pulses with characteristic flight times to focal points within the object to be inspected. The present invention calculates a virtual array equivalent in flight times to the array of N elements, where each element belonging to the array of N virtual elements is calculated from the coordinates of two foci F {sub, A} and F {sub, B }, both located on a main ray, and from the equation: t {sub, K} = t {sub, CF} + t {sub, FA} - t {sub, BF} - t {sub, FV} where t {sub, CF}, t {sub, FA}, t {sub, BF}, t {sub, FV} are the characteristic flight times, and t {sub, K} is a constant independent of the position of the focal point.
