Intra-cardiac echographies : computing myocardium deformations

Collaboration	:	Methodist Hospital Research Institute / Dirar Khoury MD Center for Mathematical Biosciences / Robert Azencott , Yi Peng Li
Data	:	Ultra-sound movies of beating heart (30 views / sec)
Goal	:	Automatic extraction of Myocardium motion field
Challenge	:	Presence of strong random “Speckle Noise.”
Mathematics	:	Minimize a Stochastic Cost Functional to extract a vector field of non linear deformations
