Abstract
The present specification describes a scanning/inspection system configured as a dual-view system using dual-energy sensitive stacked detectors that are partially populated with multi-energy discriminating detectors for overall enhanced energy resolution and therefore improved discrimination of materials through better estimation of material physical properties such as density and effective atomic number.
Claims18
A system for screening objects, comprising:
- a) a receptacle for holding an object;
- b) a conveyor to move the receptacle through an inspection region;
- c) a first X-ray source for transmitting X-rays through the object for generating a vertical X-ray projection view of the said object;
- d) a second X-ray source for transmitting X-rays through the object for generating a horizontal X-ray projection view of the said object;
- e) a first set and a second set of transmission detectors for receiving the X-rays transmitted through the said object;
- and
- f) a third and a fourth set of energy discriminating detectors for receiving the X-rays transmitted through the said object, wherein said third and fourth set of energy discriminating detectors are positioned such that they align with the object within the receptacle.

A method for screening objects, comprising:
- a) providing a receptacle to hold and align an object;
- b) moving the said receptacle through an inspection region using a conveyor;
- c) generating a vertical X-ray projection view of the said object using a first X-ray source;
- d) generating a horizontal X-ray projection view of the said object using a second X-ray source;
- e) detecting X-rays transmitted through the said object using a first set and second set of transmission detectors;
- and
- f) detecting X-rays transmitted through the said object using a third set and fourth set of energy discriminating detectors which are positioned such that they align with the object within the receptacle.
