A moiré frequency derivation section determines frequency of the moiré that appears in the fluoroscopic X-ray image, a defective pixel preliminary complement section forms a preliminary complement image, a moiré removal section conducts frequency analysis of the preliminary complement image to form a moiré removed image, an image smoothing section performs an image smoothing process to the preliminary complement image to form a smoothed image suitable for complement of the defective pixel, and a first defective pixel recomplement section recomplements the defective pixel by superimposing the moiré removed image on the smoothed image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of removing moiré in fluoroscopic X-ray image and X-ray imaging equipment using the same","description":"Provided is a method of removing a moiré in a fluoroscopic X-ray image that preliminarily complements a defective pixel with no disturbance in regularity of a moiré pattern to ensure that no trace of ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8538118","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.
