The source grating is misaligned in respect to an interferometer such that moiré fringes are detectable in the plane of the detector. A translation signal is computed for translating the source grating for achieving a predetermined moiré pattern. The positioning of the source grating is adjusted in an X-ray projection direction based on the translation signal such that at least 2 pi of phase changes are covered with the Moiré fringes over the width of the detector. And a further differential phase contrast imaging X-ray scan is acquired."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Aligning source-grating-to-phase-grating distance for multiple order phase tuning in differential phase contrast imaging","description":"An X-ray imaging method includes acquiring a differential phase contrast imaging X-ray scan with an X-ray imaging system having an X-ray source, an X-ray detector, and a grating arrangement having a s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9717470","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
