x-ray detector arrangement, imaging system, method for x-ray phase contrast tomosynthesis imaging, computer program element for controlling an arrangement or system, and computer readable media

摘要

The present invention relates to an x-ray detector arrangement (10) for x-ray phase contrast tomosynthesis imaging, to a line detector (1) for x-ray phase contrast tomosynthesis imaging , an imaging system (24) for x-ray phase contrast tomosynthesis imaging, a method for x-ray phase contrast tomosynthesis imaging, and a computer program element for controlling such arrangement and a media computer readable that has stored such a computer program element. The x-ray detector arrangement (10) comprises several line detectors (1). each line detector (1) is configured to detect a moire pattern on at least a portion of an x-ray beam (2) that hits such a line detector (1). each line detector (1) comprises several detector lines (11), wherein a width w of each line detector (1) is equal to a period or an integer multiple of the moire pattern period.
