Global Diffusion Tractography by Simulated Annealing.

Objective: Our goal is to develop a robust global tractography method for cardiac diffusion imaging. Methods: A graph is stretched over the whole myocardium to represent the fiber structure, and the solutions are minima of a graph energy measuring the fidelity to the data along with the fiber density and curvature. The optimization is performed by a variant of simulated annealing that offers incre...
