Popis: | Viscosity has been shown to be a tissue property of diagnostic value that plays an important role in the propagation of shear waves. Recently, system identification (SI) techniques have been proposed for the estimation of tissue viscoelasticity maps. Here, we compare the performance of SI-based viscosity imaging by multiple tracking location (MTL) shear wave elastography (SWE) and by single tracking location (STL) SWE. The latter reduces speckle bias at the cost of using multiple push pulses to map the entire field of view. |
