Method and system for modeling human heart and atrium

摘要

The present disclosure is a method and system for modeling a human heart and / or ventricles and cavities therein, such as the left and right atrium, based on a plurality of emission tomographic images, such as positron emission images of the human heart. Thus, each image represents the concentration of the injected tracer at a particular time, and the overall method is: A: Extract the time activity curve of the injected tracer for multiple pixels and / or voxels. B. identifying a first pass peak of the time activity curve, each peak corresponding to an arrival time of the injected tracer at a corresponding pixel / voxel; and C: heart. Defining a model comprising at least two parts of the first path with respect to the threshold Defining, isolated by selecting the pixels and / or voxels based on the comparison of the arcs; and D: comparing the arrival times of the first pass peaks of the pixels and / or voxels in at least two portions. Disposing at least two parts with respect to each other, thereby obtaining a segmented model of the human heart, wherein the method and model specifically comprises the left atrium or the right Methods and systems that can be used to obtain an estimate of atrial volume.
