Abstract
An X-ray imaging inspection system for inspecting items comprises an X-ray source 10 extending around an imaging volume 16, and defining a plurality of source points 14 from which X-rays can be directed through the imaging volume. An X-ray detector array 12 also extends around the imaging volume 16 and is arranged to detect X-rays from the source points which have passed through the imaging volume, and to produce output signals dependent on the detected X-rays. A conveyor 20 is arranged to convey the items through the imaging volume 16.
Claims20
An X-ray imaging system for collecting data about an object being inspected and determining a threat associated with the object, the system comprising
- an X-ray scanner for generating X-rays;
- a plurality of detectors;
- a memory having a plurality of areas each being associated with a respective area of an X-ray tomographic image;
- a data input means arranged to receive input data from the plurality of X-ray detectors in a predetermined sequence;
- processing means arranged to generate from the input data the X-ray tomographic image, wherein the processing means is further configured to
- extract a plurality of parameters from the X-ray tomographic image;
- construct information using the extracted plurality of parameters by applying one or more decision trees, wherein the information is indicative of a volume contiguity of the object being inspected;
- conduct a database search to allocate the object to a predefined safety category;
- and
- map the constructed information to a level of threat using results of the database search.
