Three integral components to build a tutoring system for echocardiography are presented. A mathematical time-varying model for vessel-representations of the human heart, based on cubic B-Splines and wavelets facilitating the extraction of arbitrarily detailed anatomical boundaries. A dedicated ontology framework the model is embedded into enabling efficient (meta-)data management as well as the automatic generation of (e.g. pathologic) heart instances based on standardized cardiac findings. A simulator generating virtual ultrasound images from instances of the heart transformed into isotropic tissue representations.
