Query: A consistent model for cardiac deformation estimation under abnormal
  ventricular muscle conditions   Deformation modeling of cardiac muscle is an important issue in the field of
cardiac analysis. For this reason, many approaches have been developed to best
estimate the cardiac muscle deformation, and to obtain a practical model to use
in diagnostic procedures. But there are some conditions, like in case of
myocardial infarction, in which the regular modeling approaches are not useful.
In this section, using a point-wise approach in deformation estimation, we try
to estimate the deformation under some abnormal conditions of cardiac muscle.
First, the endocardial and epicardial contour points are ordered with respect
to the center of gravity of endocardial contour and boundary point displacement
vectors are extracted. Then to solve the governing equation of deformation,
which is an elliptic equation, we apply boundary conditions in accordance with
the computed displacement vectors and then the Finite Element method (FEM) will
be used to solve the governing equation. Using obtained displacement field
through the cardiac muscle, strain map is extracted to show the mechanical
behavior of cardiac muscle. To validate the proposed algorithm in case of
infracted muscle, a non-homogeneous ring is modeled using ANSYS under a uniform
time varying internal pressure, which is the case in real cardiac muscle
deformation and then the proposed algorithm implemented in MATLAB and the
results for such problem are extracted.
