Abstract

Un método de reconstrucción TC de haz cónico en espiral, que comprende los pasos de: con base en el paso de un sistema de TC de haz cónico en espiral y en la distancia entre filas en una sonda multifilas, que calcula el número más pequeño de filas de sonda requerido para cubrir la ventana (S61) Tam; si el número de filas de sonda del sistema de TC de haz cónico en espiral es menor que tal número más pequeño de filas de sonda, que realiza la ponderación de los datos de proyección complementaria para compensar los datos de proyección faltantes (S62); reordenar los datos de proyección compensados en datos del haz colimado del ángulo cónico (S63); realizar la ponderación del coseno del ángulo cónico en los datos del haz colimado reordenados y después realizar el filtrado unidimensional a lo largo de la dirección de fila de una sonda virtual que se define sobre tal reordenamiento en los datos de haz colimado (S64), y realizar una retroproyección de haz colimado del ángulo cónico en los datos filtrados para obtener una imagen reconstruida (S65). También se proporciona un sistema de TC de haz cónico en espiral.
