In various embodiments, the controller operates each of the transducer element sets in accordance with a pulse-width modulation pattern having a duty cycle selected to achieve the target average intensity level, energy level, and/or temperature level at the target in accordance with a time constant of the target tissue."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultrasound focusing using a cross-point switch matrix","description":"A system for delivering ultrasound energy to an internal anatomical target includes an ultrasound transducer having multiple transducer elements collectively operable as a phased array; multiple drive","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11272904","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.
