Influences of noise components or fine structural components inside a patient M are reduced by generating the low-frequency image, which facilitates recognition of a contour shape of the patient M. The boundary pixels are selected based on the low-frequency image and the luminance variation image generated from the low-frequency image. This assures highly accurate and stable area extraction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radiological image area extracting apparatus, radiological image area extraction program, and radiographic apparatus","description":"An image area extracting device includes a low-frequency image generating unit for generating a low-frequency image from a radiological image by a frequency filter process lower than a spatial frequen","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8483470","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.
