Abstract

a presente invenção fornece um método e dispositivo para detectar um parâmetro viscoelástico de um meio viscoelástico. o método compreende: aplicar uma vibração mecânica em uma única frequência predeterminada ao meio viscoelástico para gerar uma onda de cisalhamento no meio viscoelástico (101); emitir ondas ultrassônicas para o meio viscoelástico, e receber sinais de eco ultrassônicos (102); adquirir dados de deslocamento máximo da onda de cisalhamento em várias profundidades de acordo com os sinais de eco ultrassônicos (103), cada dos dados de deslocamento máximo representando uma amplitude de oscilação máxima da onda de cisalhamento quando a onda de cisalhamento se propaga em diferentes profundidades no meio viscoelástico; ajustar cada dos dados de deslocamento máximo para obter uma curva de atenuação de deslocamento máximo (104); e determinar o parâmetro viscoelástico do meio viscoelástico de acordo com a curva de atenuação de deslocamento máximo (105). assim, um parâmetro viscoelástico relacionado tanto à elasticidade como à viscosidade pode ser adquirido para aumentar uma dimensão de medição de um tecido, facilitando o fornecimento de informações de parâmetros de tecidos e dimensões de medição mais ricas, e proporcionando um resultado de medição mais preciso da fibrose do tecido.
