X-ray scanners having source points with less than a predefined variation in brightness
First Claim
1. An X-ray scanner comprisingan X-ray source arranged to emit X-rays from a plurality of source points through an imaging volume, wherein the plurality of source points have a less than 5% variation in brightness between each of the plurality of source points;
- an array of X-ray detectors arranged around the imaging volume and arranged to output detector signals in response to the detection of X-rays;
a conveyor arranged to convey an object through the imaging volume in a scan direction; and
at least one processor arranged to process the detector signals to produce an image data set defining an image of the object.

Abstract
The present application discloses an X-ray scanner having an X-ray source arranged to emit X-rays from source points through an imaging volume. The scanner may further include an array of X-ray detectors which may be arranged around the imaging volume and may be arranged to output detector signals in response to the detection of X-rays. The scanner may further include a conveyor arranged to convey an object through the imaging volume in a scan direction, and may also include at least one processor arranged to process the detector signals to produce an image data set defining an image of the object. The image may have a resolution in the scan direction that is at least 90% as high as in one direction, and in some cases two directions, orthogonal to the scan direction.
