Abstract

trata-se de uma sonda ultrassônica (100) e um dispositivo de detecção ultrassônica fornecido com a sonda ultrassônica (100). a sonda ultrassônica (100) inclui: um arranjo de transdutor ultrassônico (110) configurado para transmitir e receber ondas ultrassônicas; um dispositivo de condução (20) disposto na extremidade frontal do arranjo de transdutor ultrassônico (110), e o dispositivo de condução (20) inclui uma câmara de fluido (130, 130') preenchida com fluido (133, 133'). a câmara de fluido (130, 130') tem uma abertura (131, 131') e uma porta de recebimento de energia (132, 132') que estão em comunicação uma com a outra, e a abertura (131, 131') é disposta em uma superfície frontal do dispositivo de condução (20) e coberta por um filme elástico (134); um dispositivo de aplicação de energia (140), conectado à porta de recebimento de energia (132, 132') para aplicar energia ao fluido (133, 133') dentro da câmara de fluido (130, 130') para fazer o filme elástico (134) vibrar de modo a gerar uma onda de cisalhamento. a presente invenção adota um arranjo de transdutor ultrassônico completo (110) para receber o sinal ultrassônico que inclui informações de onda de cisalhamento, não é necessário compensar o sinal ultrassônico obtido em virtude de interpolação e formação de feixe e similares, aprimorando adicionalmente, assim, a conveniência e a precisão da medição, alcançando, assim, uma boa qualidade de imageamento, uma quantidade pequena de processamento de dados e alta velocidade de detecção. adicionalmente, o mesmo suporta tanto a função da elastografia instantânea quanto a função combinada do imageamento ultrassônico tradicional e a elastografia instantânea.
