3D-3 Pushing the Boundaries of Ultrasound Imaging to Unravel the Subwavelength World

Current ultrasound imaging technology is limited by the tradeoff between resolution and imaging depth. While long wavelengths can penetrate deep into a medium, the classical diffraction limit precludes the possibility of observing subwavelength structures. Recently, it has been shown that subwavelength resolution can be achieved by considering more accurate models to describe the interaction between a probing wave and the object to be imaged. This papers present some new experimental results which prove that subwavelength resolution is indeed possible
