DEVICE FOR GENERATING MECHANICAL SHEAR WAVES INSIDE A SOFT MATERIAL, SHEAR WAVE IMAGING APPARATUS FOR THE SAME

摘要

The present invention relates to the field of acoustic imaging of soft materials, such as shear wave elastography. A method for generating shear waves in a soft material includes placing at least one patch including a metallic material along and in contact with an external boundary of a soft material, and applying a variable magnetic field on the patch using an electromagnet, in order to generate eddy currents circulating inside each metal strip and a Lorentz force imparting an oscillation movement of the patch.
