1. A system for identifying objects in a container, comprising:
- a. a first screening system comprising;
i. a stationary X-ray source arranged to generate X-rays from a plurality of X-ray source positions around a scanning region;
ii. a first set of detectors arranged to detect X-rays transmitted through the scanning region;
iii. a second set of detectors arranged to detect X-rays scattered within the scanning region;
iv. at least one processor configured to process data output from the first set of detectors and generate at least one tomographic image and to process data output from the second set of detectors to generate scatter image data; and
b. a second screening system comprising at least one of a NQR-based screening system, X-ray diffraction based screening system, X-ray back-scatter based screening system, or trace detection based screening system.

Abstract
The present invention provides for an improved scanning process with a stationary X-ray source arranged to generate X-rays from a plurality of X-ray source positions around a scanning region, a first set of detectors arranged to detect X-rays transmitted through the scanning region, and at least one processor arranged to process outputs from the first set of detectors to generate tomographic image data. The X-ray screening system is used in combination with other screening technologies, such as NQR-based screening, X-ray diffraction based screening, X-ray back-scatter based screening, or Trace Detection based screening.
