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.
Claims14
An X-ray imaging system for scanning an object, the system comprising:
- stationary X-ray sources configured at least partially around an imaging volume;
- detectors configured at least partially around the imaging volume, wherein the detectors are configured to detect X-rays emitted from the stationary X-ray sources and are configured to generate X-ray image data;
- at least one processor configured to execute programmatic instructions that, when executed, receive the X-ray image data and generate at least a tomographic image from the X-ray image data, wherein the at least one processor is further configured to execute the programmatic instructions to:
- determine a plurality of parameters from the X-ray image data;
- apply one or more decision trees to the determined plurality of parameters to generate an output;
- construct information based on the output;
- determine if the information is indicative of a threat;
- allocate the object to a category indicative of safety based on a probability of the threat being present;
- and
- cause the object to be automatically sorted based on the category.
