Abstract

Un procedimiento para la inspección de seguridad de un artículo líquido con TC de doble energía, que comprende las etapas de: llevar a cabo una exploración RD para obtener una imagen de transmisión vertical del artículo inspeccionado; determinar al menos un posición de exploración TC horizontal en función de al menos una fila de la imagen de transmisión vertical; adquirir datos de proyección de doble energía mediante una exploración TC de doble energía en la manera de una exploración TC en plano horizontal en el artículo líquido que va a inspeccionarse en la al menos una posición de exploración TC horizontal determinada; llevar a cabo una reconstrucción TC en los datos de proyección para obtener una imagen TC que indica una pluralidad de atributos físicos del artículo líquido inspeccionado; extraer la pluralidad de atributos físicos del artículo líquido inspeccionado en función de la imagen TC; y determinar si el artículo líquido inspeccionado es sospechoso comparando los atributos físicos extraídos del artículo líquido inspeccionado y los atributos físicos de referencia obtenidos para una pluralidad de líquidos de muestra conocidos.
