At Device Realization Lab at MIT, I am partnering with Philips research on developing a new type of shear wave elastography with mechanical vibrations. The basically idea is using two symmetric balls to vibrate in order to generate two symmetric shear waves, then along the center line of the balls, we could use ultrasound to image shear waves to calculate the speed of shear wave, which is directly correlated to the elasticity of the material being imaged. This is a potential opportunity for a low cost imaging device for diagnosis of liver fibrosis.
