The different Fresnel patterns cause the secondary lobe energy to be reduced via averaging of variations of the pressure fields in the secondary lobe regions. In some embodiments, the method of coherently compounded Fresnel focusing is combined with coherently compounded defocused wave (e.g. plane wave or diverging wave) imaging in the azimuth direction. Each of the elevation slices are collected by changing the Fresnel patterns respectively employed when the sequence of plane waves or diverging waves are transmitted, such that the coherent compounding can benefit both planes simultaneously. Hadamard receive encoding and subsequent dynamic receive beamforming may be employed to further improve performance in the elevation direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for ultrasound beamforming using coherently compounded Fresnel focusing","description":"Fresnel elevation focusing at a selected elevation angle is performed by transmitting a sequential set of Fresnel-focused ultrasound pulses, where a different Fresnel phase pattern is used for each pu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11255965","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.
