B-spline Modeling of the Left Ventricle

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.
