MR画像を用いた関節軟骨の3次元変形とひずみの計測

抄録

In this study, to evaluate the strain distribution of the articular cartilage in three-dimension, digital volume correlation method is used. Digital volume correlation program is constructed and used to measure the displacement and strain of the porcine knee joint under compressive load. The deformation of the porcine knee joint is obtained from MR image under non-compressive and compressive load. The result of the analysis of the compression experiment shows that the strains are observed at the compressive area at three-dimensions. It is possible to obtain displacement and strain distribution of the articular cartilage by using MRI.
