Abstract

método e dispositivo de detecção de elasticidade. são divulgados um método e um dispositivo para a detecção de elasticidade. o método compreende: controlar um dispositivo de excitação (2) para excitar periodicamente n ondas de cisalhamento em um tecido em um intervalo de tempo predefinido e controlar um transdutor ultrassônico (3) para transmitir ondas ultrassônicas (101) para o tecido, onde o dispositivo de excitação e o transdutor ultrassônico é mantido em contato com uma superfície do tecido; recebendo, pelo transdutor ultrassônico (3), um sinal de eco ultrassônico (102) correspondente a cada uma das ondas de cisalhamento; adquirindo um parâmetro característico de propagação (103) de cada uma das ondas de cisalhamento de acordo com o sinal de eco ultrassônico correspondente a cada uma das ondas de cisalhamento; calculando um parâmetro de elasticidade do tecido (104) de acordo com os parâmetros característicos de propagação das n ondas de cisalhamento e uma densidade tecidual do tecido. o dispositivo de excitação (2) e o transdutor de ultrassons (3) são mantidos em contato com a superfície do tecido sem localizar manualmente o dispositivo de excitação (2) várias vezes na superfície do tecido, garantindo assim que as n ondas de cisalhamento estão excitadas em relação à mesma posição, o que é útil para garantir a precisão do resultado final da detecção de parâmetros de elasticidade.
