Abstract
resumo método de controle de uma abertura de um transdutor em conjunto de uma sonda de ultrassom um transdutor em conjunto ultrassônico de duas dimensões recebe sinais de eco de profundidades crescentes de uma região volumétrica. o conjunto 2d é configurado em agrupamentos de elementos que são processados por um micro-formador de feixe, e sinais somados de um agrupamento são acoplados a um canal de um formador de feixe de ultrassom. na profundidade menor, o conjunto 2d recebe ecos de agrupamentos pequenos no centro da abertura. conforme sinais são recebidos de profundidades crescentes, a abertura aumenta pela adição simétrica de agrupamentos de tamanhos progressivamente maiores em qualquer lado dos agrupamentos pequenos no centro. a técnica de invenção pode aprimorar o desempenho multilinha das sondas de conjunto 1d e 2d. 1/1
