Abstract:
A device with modularized units for inspecting a container, the device comprising:a first modular cabin unit (2) within which a radiation source is mounted for generating a beam of penetration radiation for penetrating the container to be inspected; a second modular cabin unit (6) within which detectors (10) are mounted for detecting the beam of penetration radiation penetrating through the container being inspected and producing corresponding radiographic signals, the second modular cabin unit (6) and the first modular cabin unit (2) being arranged in spaced relationship from each other to define an inspection passage and wherein the first and second modular cabin units (2, 6) are at opposite sides of the inspection passage; a modular gantry unit (3, 4, 5) joined to and bridging the first modular cabin unit (2) and the second modular cabin unit (6) to form a portal-shaped frame adapted for straddling the container being inspected, and additional detectors (11, 12) being mounted within the modular gantry unit (3, 4, 5); means for a moving the first and second modular cabin units (2, 6) and the modular gantry unit (3, 4, 5) in unison relative to the container being inspected along the inspection passage, so that the detectors (10, 11, 12) receive the beam of the penetration radiation generated from the radiation source and passing through the container being inspected, thereby continuously scanning the container and producing the corresponding radiographic signals, wherein the first modular cabin unit (2), the second modular cabin unit (6) and the modular gantry unit (3, 4, 5) are each individual modular units that are quickly and easily joined together and separable from each other at an inspection site.
