Ultrasound elastography measures the elastic properties of soft tissues using ultrasound signals. The elastic
problem can be analyzed with tensor signal processing. In this work, we propose a new interpretation of elastography
through the deformation tensor and its decomposition into both the strain and vorticity tensors. Vorticity
gives information about the rotation of the inclusions that might help in the discrimination between malign
and benign tumors without using biopsy. Although clinical validation is needed, synthetic experiments present
reliable results.
