Abstract
The present specification discloses a covet mobile inspection vehicle with a backscatter X-ray scanning system that has an X-ray source and detectors for obtaining a radiographic image of an object outside the vehicle. The systems preferably include at least one sensor for determining a distance front at least one of the detectors to points on the surface of the object being scanned, a processor for processing the obtained radiographic image by using the determined distance of the object to obtain an atomic number of each material contained in the object, and one or more sensors to obtain surveillance data from a predefined area surrounding the vehicle.
Claims22
An inspection system comprising:
- an X-ray scanning system comprising an X-ray source configured to emit X-ray beams and a plurality of detectors configured to acquire data representative of a radiographic image of an object located outside the inspection system;
- one or more sensors adapted to determine data representative of a distance from at least one of the plurality of detectors to an area on a surface of the object;
- and
- a processor configured to process the obtained radiographic image, wherein the processor is configured to apply a correction to the obtained radiographic image based on the determined data representative of the distance.
A method for obtaining a radiographic image of an object located outside of an inspection system, comprising:
- using an X-ray source configured to emit X-ray beams;
- acquiring data representative of the radiographic image of the object using a plurality of detectors;
- determining, using one or more sensors, data representative of a distance from at least one of the plurality of detectors to an area on a surface of the object;
- and,
- processing the obtained radiographic image using a processor, by applying a correction to the obtained radiographic image based on the determined data representative of the distance.
