Abstract

sistema de geração de imagem para a geração de imagem de um meio viscoelástico, dispositivo de ablação e método de operação de um sistema de geração de imagem um sistema de geração de imagem para a geração de imagem de um meio viscoelástico é revelado. o sistema de geração de imagem compreende uma lente refrativa variável (4) e um sistema transdutor (5) para a geração de radiação acústica. o sistema de geração de imagem é operado para alternar entre o primeiro e o segundo modos de operação. enquanto a lente refrativa variável é operada para alternar entre uma primeira configuração e uma segunda configuração, o transdutor é operado para alternar entre a geração de radiação acústica para o deslocamento do meio viscoelástico e a radiação acústica para a geração de imagem de deslocamento do meio viscoelástico. em algumas configurações, a lente refrativa variável é uma lente de foco fluido. além disso, em algumas configurações, o sistema de geração de imagem é integrado a uma modalidade de interação com base em cateter, tal como uma modalidade de ablação de tecido.
