LOSS-ANGLE-BASED DETERMINATION OF A MEDIUM VISCOELASTIC PARAMETER IN SUB-HERTZ FREQUENCY RANGE WITH THE USE OF LOCAL CREEP RESPONSE

摘要

System and method configured to characterize viscoelasticity of a target medium by directly determining phase difference between reai and imaginary parts of the complex shear modulus of the tissue (determined as a result of applying a compression force to the tissue), and without any fitting of data and independent from distribution of strain in tiie tissue caused by the application of compression force.
