Abstract

L'invention porte sur un système d'émission de rayons X, à mode variable, qui peut fonctionner dans des modes à débit de dose faible ou élevé, en fonction de la zone ou de la partie du véhicule à examiner. Dans un mode de réalisation, un débit de dose variable est obtenu par l'utilisation d'un nouveau collimateur. Les systèmes selon l'invention permettent le balayage d'une partie de cabine de véhicule (occupée par des personnes, telles qu'un conducteur) à un faible débit de dose, qui est sans danger pour des êtres humains, tout en permettant le balayage de la partie de chargement (inoccupée par des personnes) à un débit de dose élevé. Une commutation rapide entre les modes de fonctionnement à faible débit de dose et à débit de dose élevé est fournie, tout en produisant un équilibre entre une pénétration de matériau élevée pour la partie de chargement et une exposition de faible intensité qui est sans danger pour des occupants dans la partie de cabine du véhicule inspecté.
