The spline mesh is obtained by fitting 12 points in spherical coordinate
system over a rectangular patch of size 2PI x PI, azimuth and elevation
respectively. The patch is divided into a 32x32 net, giving 512 points
that are converted back into cartesian coordinate system and plotted.
The algorithm for approximation/interpolation of a cloud of points by a B-spline surface is provided by Professor George Wolberg.
|The points are obtained by attaching
Sonometrics sensors onto the
LV surface and into the septum. Datasets are provided by
Marc Dickstein, MD, Columbia Presbiterian Hospital, New York.
