Abstract
An X-ray device, array and method for performing digital X-ray imaging. An X-ray device has an X-ray source that is disposed on a substantially opposite side of an object to be analyzed from a digital X-ray detector. The digital X-ray detector may be formed as an array having a plurality of detectors, and the device may have a plurality of arrays. The detector moves linearly relative to the object along an axis.

An X-ray device for tomosynthesis, the device comprising:
- an X-ray source for emitting X-ray radiation at an object in a first direction;
- and
- at least one digital X-ray detector array having a plurality of detectors, each detector comprising a two-dimensional matrix of detection elements, wherein the at least one detector array is located on a substantially opposite side of the object from the X-ray source, wherein a line parallel to a scanning axis intersects at least two of the plurality of detectors in the detector array, and wherein the at least one detector array is configured such that it:
- moves, in a single pass, linearly relative to the object along the scanning axis which is substantially perpendicular to the first direction;
- receives, during the single pass, X-ray radiation that has passed through a region of interest of the object from a plurality of incident angles;
- and
- provides, based on the X-ray radiation received during the single pass, an electronic signal that represents an X-ray image of the region of interest.
