An experimental 3D ultrasound elastography setup has been designed for breast cancer diagnosis improvement. 3D elastography assessment is generally based on the combination of adjacent 2D elasticity maps, obtained through simple 2D inverse problem resolution. Meanwhile, 3D sonoelastography is based on simple inversion approaches to the viscoelasticity problem. The system presented here is based on...
Supersonic shear imaging (SSI) is a new ultrasound-based technique for real-time visualization of soft tissue viscoelastic properties. Using ultrasonic focused beams, it is possible to remotely generate mechanical vibration sources radiating low-frequency, shear waves inside tissues. Relying on this concept, SSI proposes to create such a source and make it move at a supersonic speed. In analogy with...
