Abstract (EN)
This paper presents different ways to use the Doppler Tissue Imaging (DTI) in order to determine deformation of the cardiac wall. As an extra information added to the ultrasound images, the DTI gives the velocity in the direction of the probe. We first show a way to track points along the cardiac wall in a M-Mode image (1D+t). This is based on energy minimization similar to a deformable grid. We then extend the ideas to finding the deformation field in a sequence of 2D images (2D+t). This is based on energy minimization including spatio-temporal regularizatio.
