Abstract
The present specification discloses an X-ray scanning system with a non-rotating X-ray scanner that generates scanning data defining a tomographic X-ray image of the object and a processor executing programmatic instructions where the executing processor analyzes the scanning data to extract at least one parameter of the tomographic X-ray image and where the processor is configured to determine if the object comprises a liquid, sharp object, narcotic, currency, nuclear materials, cigarettes or fire-arms.
Claims80
An X-ray scanning system comprising:
- an X-ray scanner configured to generate scanning data defining a tomographic X-ray image of an object, wherein the X-ray scanner comprises an imaging volume and a plurality of X-ray sources, positioned at least partially around the imaging volume, from which X-rays are directed through the imaging volume, and wherein the X-ray scanner is configured to mimic a rotational motion of the plurality of X-ray sources without physically moving each of the plurality of X-ray sources;
- and
- at least one processor configured to analyze the scanning data to determine at least one parameter of the tomographic X-ray image and to determine if the object comprises a detonator.
An X-ray scanning system comprising:
- an X-ray scanner configured to generate scanning data defining a tomographic X-ray image of an object, wherein the X-ray scanner comprises an imaging volume and a plurality of X-ray sources, positioned at least partially around the imaging volume, from which X-rays are directed through the imaging volume and wherein the X-ray scanner is configured to mimic a rotational motion of the a plurality of X-ray sources without physically moving each of the plurality of X-ray sources;
- and
- at least one processor configured to analyze the scanning data to determine at least one parameter of the tomographic X-ray image and to determine if the object comprises a gun.
An X-ray imaging inspection system configured to generate a three dimensional image of at least one object, comprising:
- a plurality of X-ray sources distributed at least partially around an imaging volume, wherein the plurality of X-ray sources are configured to emit X-rays which are directed through the imaging volume and wherein the X-ray imaging inspection system is configured to mimic a rotational motion of the plurality of X-ray sources without physically moving each of the plurality of X-ray sources;
- an X-ray detector array extending at least partially around the imaging volume and configured to detect X-rays from the plurality of X-ray sources which have passed through the imaging volume and to produce output signals dependent on the detected X-rays;
- a conveyor arranged to convey the at least one object through the imaging volume;
- and
- at least one processor configured to analyze the output signals to generate the three dimensional image and determine if the at least one object comprises a security threat.
An X-ray imaging inspection system configured to generate a three dimensional image of at least one object, comprising:
- a plurality of X-ray sources extending at least partially around an imaging volume, wherein the plurality of X-ray sources are configured to emit and direct X-rays through the imaging volume and wherein the X-ray imaging inspection system is configured to mimic a rotational motion of the plurality of X-ray sources without physically moving each of the plurality of X-ray sources;
- an X-ray detector array extending at least partially around the imaging volume and configured to detect X-rays from the plurality of X-ray sources which have passed through the imaging volume and to produce output signals dependent on the detected X-rays, wherein the X-ray detector array includes a plurality of detectors comprising at least one of GaAs, HgI, CdZnTe or CdTe;
- a conveyor arranged to convey the at least one object through the imaging volume;
- and
- at least one processor configured to analyze the output signals to generate the three dimensional image and identify if the at least one object comprises a security threat;
- and
- a plurality of programmatic instructions that, when executed by the at least one processor, produces a control output that automatically sorts the at least one object into one of a plurality of categories, wherein the plurality of categories comprises a clear category and a not clear category.
