Fitting 𝐶² Continuous Parametric Surfaces to Frontiers Delimiting Physiologic Structures

Figure 3

Polygonal surfaces (Figure 2), projected onto the (𝑢−𝑣) parametric plane. The surfaces delineate the endocardial surface of the right ventricular cavity (a), the endocadial surface of left ventricular cavity (b), and the epicardial surface (c).
