Left ventricle 3D reconstruction using Gibbs random fields and simulated annealing

Abstract:

A left ventricle three dimensional reconstruction method from two orthogonal X-ray angiographic projections is presented. The algorithm works under the assumption that there are two segmented parallel projections and a homogeneous mixture of blood and contrast agent, to develop 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-dimensional profiles corresponding to a pair of rows obtained from the segmented projections. Performance of the reconstruction method was evaluated with preprocessed ventricular angiographic images and a 3D binary database. Results show a reconstruction error of less than 7%.
