An auto adaptive analysis method about rapidly and accurately extracting a TIC tendency of the contrast imaging method based on the wide beam is also provided to overcome limitations of a decrease in the CTR of the contrast imaging based on the wide beam and a decrease in SCR of the perfusion TIC. The present invention plays an important role in effectively reducing an ultrasound contrast imaging acoustic power and a contrast microbubble perfusion concentration, reducing potential threat to human body, acquiring a contrast image with the high CTR, and accurately evaluating and diagnosing blood perfusion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Contrast imaging method based on wide beam and method for extracting perfusion time-intensity curve","description":"A contrast imaging method based on a wide beam and a method for extracting a perfusion time-intensity curve (TIC) are provided to increase contrast-to-tissue ratio (CTR) through the contrast imaging m","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9788815","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.
