Abstract

To accurately generate an improved, anatomically correct reconstruction (e.g., map) of atrial anatomy.SOLUTION: A method is provided for generating an anatomically correct reconstruction of an atrium using a machine learning / artificial intelligence algorithm. The method includes receiving, by a reconstruction engine executed by processors, inputs corresponding to an anatomical structure, and computing, by a model-based fast anatomical mapping of the reconstruction engine, an initial transformation that selects a parametric model that best fits the inputs. The method further includes executing, by the model-based fast anatomical mapping, an iterative optimization. The iterative optimization includes constructing a statistical prior distribution based on the parametric model, and applying the parametric model to the inputs and the statistical prior distribution to produce an isosurface of the anatomical structure. The method further includes generating, by the reconstruction engine, an output including the isosurface.SELECTED DRAWING: Figure 1
