Measurement Accuracy of Ultrasound Viscoelastic Creep Imaging in Measuring the Viscoelastic Properties of Heterogeneous Materials

Ultrasound viscoelastic creep imaging (UVCI) is a newly developed technology aiming to measure the properties of materials. The purpose this study investigate accuracy UVCI in measuring heterogeneous materials that mimic pathological lesions and normal tissues. finite element simulation used measurement on three material models, including homogeneous material, single-inclusion phantom, three-layer structure. for property determined by difference between simulated result its true value defined during process. results show general cannot accurately values demonstrating need further improve theories technologies relevant tissue-like
