Este trabajo describe un sistema semiautomático, fundamentado en técnicas asistidas por computadora, que permite valorar el funcionamiento del ventrículo izquierdo en imágenes ventriculográficas. El estudio se centra en el análisis de dos instantes del ciclo cardiaco: diástole y sístole final. El proceso de segmentación es realizado de forma manual por parte del especialista utilizando una herramienta interactiva. La valoración del movimiento regional de la pared ventricular es obtenida a través de la cuantificación del desplazamiento a lo largo de 100 radios generados entre los dos contornos ventriculares; con estas mediciones es posible generar una valoración porcentual de radios normales, hyperkinéticos e hypokinéticos.
