Abstract
In an x-ray system and a method for tomosynthetic scanning of a subject, x-ray radiation is emitted from two x-ray sources that are panned along a line relative to the subject during a tomosynthetic scan. The two x-ray sources are located next to each other along the line, and each emit an x-ray beam. X-rays from the two parallel beams attenuated by the subject are detected by a two-dimensional x-ray detector, that is substantially stationary during the tomosynthetic scan.
Claims22
An x-ray system for tomosynthetic scanning of a subject, comprising:
- two x-ray sources that each emit an x-ray beam, said x-ray beams proceeding toward a subject to be irradiated with the x-ray beams;
- said x-ray sources being movable along a line relative to the subject to execute tomosynthetic scanning of the subject with said x-ray beams, said x-ray sources being located next to each other along said line;
- and
- a two-dimensional x-ray detector disposed behind the subject, with respect to propagation of said x-ray beams, said x-ray detector detecting x-rays in said x-ray beams attenuated by the subject, said x-ray detector being disposed substantially stationary relative to the subject during said tomosynthetic scanning.

A method for tomosynthetic scanning of a subject, comprising:
- activating two x-ray sources emit an x-ray beam from each of said x-ray sources;
- irradiating a subject with the parallel x ray beams;
- moving said x-ray sources along a line relative to the subject to execute tomosynthetic scanning of the subject with said x-ray beams, and arranging said x-ray sources next to each other along said line;
- with a two-dimensional x-ray detector disposed behind the subject and substantially stationary relative to the subject, detecting x-rays in said x-ray beams attenuated by the subject during said tomosynthetic scanning;
- and
- generating an x-ray image from the x-rays detected by said x-ray detector.
