Abstract: |
This paper proposes a method
of constructing a dynamic model of a ventricle based on isogeometric
simulation so as to diagnose cardiac disease more accurately. Isogeometric simulation is an accurate simulation technology
based on NURBS, which has evolved into an essential tool for a
semi-analytical representation of geometric entities. Especially, a new
method of moving control points is used to achieve a dynamic model of the ventricle.
This method promises the model to be very accurate, efficient, and successive,
in comparison with traditional models. Furthermore, the paper also puts forward
a new error estimation method, which adopts the vector norm to get an overall
analysis of the error coefficient in each direction. The error estimation method
avoids a complicated estimation for each knot. It can not
only be used to evaluate the value of the error accurately, but also reduce
the local error by adjusting the control points. Moreover, the proposed NURBS
model can especially be useful to analyze the motion and dynamics of the
heart, and it is important for doctors to find early cues of cardiac
diseases. |
