Sound Touch Elastography (STE) with reliability map allows clinicians to get real-time 2D elastography and Young’s modulus quantification for liver and tissue assesment. Sound Touch Quantification (STQ) with unique “E Avg” also enables real-time and easy tissue stiffness quantification for hepatic fibrosis. Natural Touch Elastography for tumor infiltration analysis provides high stiffness sensitivity in applications such as thyroid, breast, and GYN.
