Measurement of the quadriceps muscle displacement and strain fields with ultrasound and Digital Image Correlation (DIC) techniques

摘要

Objectives - In vivo characterization of muscle tissues is necessary to increase the understanding of musculoskeletal pathologies. Currently, few imaging techniques are able to characterize the in vivo mechanical properties of muscle. Thus, the purpose was to couple experimental and numerical tools to characterize the displacement and strain fields. This approach was validated on a phantom and then applied in vivo on thigh muscles.
