Abstract
A new method for shape reconstruction in cardiac MRI is presented in this work. Using a combined shape representation and local basis functions this method models the shape of the left ventricle. To solve this problem of shape reconstruction a non - linear approach is required. Fitting the model to the data is done by an iterative non-linear method, which reconstructs both the intensity and the contour. Results are shown for an undersampled set of ten k-space profiles.
