IMAGING SYSTEM FOR IMAGING A VISCOELASTIC MEDIUM

摘要

An imaging system for imaging a viscoelastic medium is disclosed. The imaging system comprises a variable refractive lens (4) and a transducer system (5) for generating acoustic radiation. The imaging system is operated to alternate between first and second operating modes. While the variable refractive lens is operated to alternate between a first configuration and a second configuration, the transducer is operated to alternate between generating acoustic radiation for displacing the viscoelastic medium and acoustic radiation for imaging the displacement of the viscoelastic medium. In embodiments the variable refractive lens is a fluid focus lens. Moreover, in embodiments, the imaging system is integrated with a catheter-based interaction modality, such as a tissue ablation modality.
