The image correction section sets a correction coefficient based on the distance information, generates a correction reference image or a correction fluoroscopic image by performing a power calculation for light intensity information of the reference image and/or the fluoroscopic image by using the correction coefficient as an index, and divides the correction fluoroscopic image by the correction reference image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fluoroscopy apparatus and fluoroscopy method","description":"A fluoroscopy apparatus that includes an illumination section including a light source for radiating illumination light and excitation light onto a subject; a fluoroscopic image acquisition section ac","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8481972","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.
