The A-scan signal matrix including 21 views is acquired. Based on Fermat's principle, the refracted points at the interface between wedge and sample for the 21 views are calculated, to obtain the corresponding amplitude for each view in the ROI. For each reconstruction point, the strongest response is selected from the 21 views. The profiles of the cracks with different orientation angles are reconstructed by CTFM."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for reconstructing crack profiles based on composite-mode total focusing method","description":"A method for reconstructing the crack profiles based on the composite-mode total focusing method (CTFM), including: selecting the parameters for phased array ultrasonic testing; acquiring the A-scan s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12007362","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.
