Abstract (English):	X-rays angiograms of the left ventricle as the main cavity of the human heart are acquired at the catheterization rooms routinely in order to evaluate the cardiac dynamic function. The global measurement of volumes, ejection fraction and synergistic motion associated with the ventricular cavity are considered in the assessment of such function. A precise left ventricle silhouette on the angiograms is necessary to calculate the function descriptors. A segmentation method is required to obtain the projected cavity shape [ABSTRACT FROM AUTHOR]
Abstract (Spanish):	Los angiogramas de rayos X del ventrículo izquierdo como la cavidad principal del corazón humano se adquieren en las salas de cateterismo de forma rutinaria para evaluar la función dinámica cardíaca. La medición global de los volúmenes, la fracción de eyección y el movimiento sinérgico asociados con la cavidad ventricular se consideran en la evaluación de dicha función. Es necesaria una silueta precisa del ventrículo izquierdo en los angiogramas para calcular los descriptores de funciones. Se requiere un método de segmentación para obtener la forma de la cavidad proyectada. [ABSTRACT FROM AUTHOR]
