| Abstract: | In order to extract and reconstruct 3-D motion and material information from cardiac cine-MR image data sequences, the continuous biomechanics model with prior knowledge of myocardial material properties is used as the constraint widely.Most researches deal with cardiac motion analysis and material parameters analysis separately,which results in increased noise and reduced reliability of estimation results.This paper proposes a noval method based on the finite-element method and an extended Kalm... |
