  • Acoustic radiation force impulse

    Acoustic radiation force impulse

    Acoustic radiation force impulse (ARFI) imaging involves the mechanical excitation of tissue using localized, impulsive radiation force. This results in shear-wave propagation away from the region of excitation. Using a single diagnostic transducer on a modified commercial ultrasound (US) scanner with conventional beam-forming architecture, repeated excitations with multiple look directions facilitate imaging shear-wave propagation.

  • Spatially Modulated Ultrasound Radiation Force (SMURF)

    Spatially Modulated Ultrasound Radiation Force (SMURF)

    Changes in tissue stiffness have long been associated with disease. Quantification of tissue stiffness is needed to reveal diffuse disease, e.g. liver fibrosis. There is strong evidence that in some cases quantification of tissue stiffness can supplement or replace hazardous biopsy methods. More info...
