Abstract

um método de realização de imagiologia acústica inclui: seleção de uma localização alvo e a seleção de um grupo de transdutores a partir de uma pluralidade de transdutores para transmitir um feixe acústico direcionado eletronicamente a localização alvo; seleção de um transmissor tendo uma orientação em direção a uma localização próxima a localização alvo e transmitindo um sinal acústico somente pelo transmissor; detecção de um sinal de retorno acústico pelo transmissor e por uma pluralidade de outros transdutores no grupo; estimativa de um tempo de deslocamento para cada um do grupo de transdutores, a estimativa incluindo a medição de um tempo de deslocamento para cada um dos outros transdutores, e estimativa de um tempo de deslocamento para o transmissor com base no tempo de deslocamento para cada um dos outros transdutores; e cálculo dos atrasos de formação de feixe com base no tempo de deslocamento, o atraso de formação de feixe configurado para fazer com que o grupo de transdutores direcione um feixe acústico para a localização alvo.
