Electromagnetic-Acoustic (EMA) imaging of stiffness and dielectric properties in gels

Journal article

Here we present a novel multi-modal imaging method, electromagnetic- acoustics (EMA) that combines acoustic radiation force and electromagnetic scattering. Experiments were carried out in gels using a focused megahertz ultrasound source, amplitude modulated at 160 Hz, to create an oscillating radiation force resulting in vibration of the gel in the focal region. At the same time a 434 MHz EM signal was transmitted into the gel and the backscattered EM signal recorded. The tissue that was in m...
