In this invited paper, an overview of techniques developed at the Cardiovascular Image Analysis Laboratory at Washington University is discussed. At the core of the authors' methodologies lie flexible shape models, which are employed in automated as well as semi-automated analysis of cardiac MRI and X-ray angiography images. The mathematical bases used for the flexible templates are of the B-spline variety, providing compact representation and interactive capabilities for manipulation of curves, surfaces, and volumes.
