Current research is presented in which both left and right ventricular deformation is estimated from tagged cardiac magnetic resonance imaging using volumetric deformable models constructed from nonuniform rational B-splines (NURBS). Based on the shape of the left ventricle two 'base surface' parameterizations are investigated---the prolate sphere and the cylinder. The typical formulation of NURBS objects employs a control point Cartesian basis. However, extending the control point basis to include both a prolate-spheroidal and a cylindrical description leads to the consideration of four model types for strain analysis: Cartesian-based NURBS models with both a cylindrical and prolate-spheroidal parameterization, prolate spheroidal-based NURBS models with a prolate-spheroidal parameterization, and cylindrical-based NURBS models with a cylindrical parameterization.

520 $a Current research is presented in which both left and right ventricular deformation is estimated from tagged cardiac magnetic resonance imaging using volumetric deformable models constructed from nonuniform rational B-splines (NURBS). Based on the shape of the left ventricle two 'base surface' parameterizations are investigated---the prolate sphere and the cylinder. The typical formulation of NURBS objects employs a control point Cartesian basis. However, extending the control point basis to include both a prolate-spheroidal and a cylindrical description leads to the consideration of four model types for strain analysis: Cartesian-based NURBS models with both a cylindrical and prolate-spheroidal parameterization, prolate spheroidal-based NURBS models with a prolate-spheroidal parameterization, and cylindrical-based NURBS models with a cylindrical parameterization.
520 $a For each frame subsequent to end-diastole, a NURBS model is constructed by fitting two surfaces with the same parameterization to the corresponding set of epicardial and endocardial contours from which a volumetric model is created. Using normal displacements of the three sets of orthogonal tag planes as well as displacements of contour/tag line intersection points and tag plane intersection points, one can solve for the optimal homogeneous coordinates, in a weighted least squares sense, of the control points of the deformed NURBS model at end-diastole using quadratic programming. This allows for subsequent forward displacement fitting from end-diastole to all later time frames. After fitting to all time points of data, lofting the NURBS model for all time points creates a comprehensive 4-D NURBS model. From this model, we can extract 3-D myocardial deformation fields and corresponding strain maps which are local measures of non-rigid deformation.
