Abstract
La invención proporciona un método para estimar una tasa de recuento de entrada de un detector de pulsos de radiación a partir de una señal del detector, donde algunos pulsos de señales individuales que componen la señal del detector están estrechamente espaciados en el tiempo menos de un espacio mínimo de detección confiable (104,105; tc, td). En un aspecto, los pulsos de señales individuales se detectan usando un algoritmo de detección y una pluralidad de tiempos de inicio de intervalo (sk) se definen cada uno interpuestos con por lo menos uno de los tiempos de llegada de pulsos de señales individuales (tk), en donde cada tiempo de inicio de intervalo (sk) está retrasado en por lo menos un espacio mínimo de detección confiable en comparación con el tiempo de llegada de pulsos de señales individuales ( tk-1). Se calcula una pluralidad correspondiente de intervalos de llegada de pulsos de señales individuales entre cada uno de los tiempos de inicio de intervalo (sk) y un siguiente tiempo de llegada de pulsos de señales individuales detectado correspondiente ( tk).
