We present a method for the estimation of the displacement field in 2D CSPAMM tagged image time series for both ventricles which does not rely on a previous detailed segmentation of the myocardial contours. the automa...

Before a retrospective registration algorithm can be used routinely in the clinic, methods must be provided for distinguishing between registration solutions that are clinically satisfactory and those that are not [1]...
