title: Evaluation of models.
abstract: Evaluation of models describing computer based technology is crucial for further evolution of medical progress. In this project, the research sites of the Sonderforschungsbereich 414 "Computer and sensor aided surgery" were linked for evaluation purposes. Topics of flow, morphology, function, and robotics in the field of cardiac and oromaxillofacial surgery are addressed. Key methods are animal models, phantoms, image processing and clinical studies in the setting of exactly defined circumstances. As an example, 3D evaluation of myocardial edema is presented. Heterogeneity of 3D distribution of induced myocardial edema was validated. Temporal dynamics of edema is described as an example. Based on such models, diagnostic and operation relevant planning data are offered to cardiac surgeons.
