A method for the three-dimensional reconstruction of the ventricular epicardial surface and its motion by biplane coronary angiography allows for a more complete use of available motion data.
Describes a computational geometry approach to reconstruct 3D ventricular epicardial surfaces and motion from biplane coronary angiography.
May improve ventricular motion assessment via routine angiography; extends computational methods but leaves validation open.
A method for the three-dimensional reconstruction of the ventricular epicardial surface and its motion by biplane coronary angiography is illustrated and discussed. An estimate of the epicardial surface is obtained by minimizing a smoothness functional over the set of all the surfaces satisfying the input-data constraints. A specific smoothness function is described. A similar approach is applied to estimate the epicardial displacement field. In this way a more complete use of available motion data as well as a full utilization of kinematic descriptors of heart motion is made possible.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
