Resumen
X-rays angiograms of the left ventricleas the main cavity of the human heartare acquired at the catheterizationrooms routinely in order to evaluate the cardiac dynamicfunction. The global measurement of volumes, ejectionfraction and synergistic motion associated with the ventricularcavity are considered in the assessment of suchfunction. A precise left ventricle silhouette on the angiogramsis necessary to calculate the function descriptors. Asegmentation method is required to obtain the projectedcavity shape
