Elasticity imaging is a non-invasive imaging technique used to assess the mechanical properties of tissue. It involves measuring the stiffness or elasticity of tissues using imaging modalities such as ultrasound, magnetic resonance imaging (MRI), and optical coherence tomography (OCT). This technique has potential applications in diagnosing diseases, monitoring treatment effectiveness, and guiding interventions. Elasticity imaging can provide valuable information about tissue structure and function, offering a complementary perspective to traditional imaging techniques.
