Abstract

This paper proposes a left ventricle tridimensional reconstruction method from two orthogonal X-rays angiographic projections. The algorithm works under the assumption of having two segmented parallel projections and an homogeneous mixture of blood and contrast agent, in order to develop a binary reconstruction based on a Markov Random Field model and Simulated Annealing. The 3D ventricular object is considered as a stacked bidimensional slice set and each slice is reconstructed from the two one-dimensional profiles corresponding to a pair of rows obtained from the segmented projections. Each bidimensional slice is described in a polar
