Abstract

dispositivo para medir propriedades viscoelásticas de tecidos biológicos e processo que utiliza esse dispositivo. a presente invenção refere-se a um dispositivo (30, 50) destinado a medir propriedades viscoelásticas de tecidos biológicos, graças a um tratamento de ondas ultrassonoras refletidas por esses tecidos, quando são percorridos por uma onda de cisalhamento, esse dispositivo compreendendo: meios (m1, m2, m3) para formar linhas (l1, l2, l3) compreendendo dados relativos às ondas ultrassonoras refletidas a partir de um mesmo tiro, meios para determinar um parâmetro relativo (3b) ao deslocamento entre os tecidos e um transdutor que emite os tiros, e meios (36) para calcular um deslocamento intrínseco (3d) do meio a partir de um conjunto de linhas (l1, l2, l3), formando uma aquisição (3a). de acordo com a invenção, esse dispositivo é caracterizado pelo fato de compreender meios para tratar de primeiras linhas (l1, l2), ultrassonoras, com o auxílio do parâmetro relativo (3b), antes da ou durante a formação de segundas linhas (l3) ultrassonoras dessa mesma aquisição (3a), a fim de determinar um deslocamento intrínseco (3d) dos tecidos biológicos.
