We propose a tensor analysis of elastography. The tensor strain field visualizes in one image the standard scalar parameters that are usually represented separately in elastography. By using strain tensor elastography (STE), physicians would have complementary information. To validate the method and the visualization scheme, ultrasound simulations based on FE software and an experiment on a commercial tissue-mimicking breast phantom were carried out. In this work, we present the theory and procedure to visualize the strain tensor field in an effort to better determine tumor infiltration, supported by a phantom study. This tensorial approach as well as its visualization can be extended to other elasticity imaging techniques.
