The tissue inflammation detection unit is configured to: determine a tissue contribution from a first wavelength region of a diffuse reflective spectroscopy signal where the diffuse reflective spectroscopy signal is dominated by tissue; extrapolate the tissue contribution to a second wavelength region where the diffuse reflective spectroscopy signal includes at least one detectable hemoglobin absorption feature; subtract the extrapolated tissue contribution from the diffuse reflectance signal; and determine the degree of tissue inflammation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical method for gingivitis detection","description":"A tissue inflammation detection system (600) including: a light emitter (602) configured to emit light towards tissue (604); at least one light detector (606) configured to detect diffuse reflective l","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11998300","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.
