Method and system for modeling human heart and atrium

摘要

The present invention relates to a method and system for modeling human hearts and / or chambers and their orifices, such as the left and right atria, based on a plurality of tomographic images, such as positron emission images of the human heart, wherein Each image represents the concentration of the tracer injected at a particular time, and the overall method comprises the following steps: A: extracting the time-activity curve of the injected tracer for a plurality of pixels and / or voxels; B: identifying a first pass peak of the time activity curve, wherein each peak corresponds to a time of arrival of the injected tracker in the corresponding pixel / voxel; C: defining a model comprising at least two portions of the heart, wherein the at least two portions are separated by selecting pixels and / or voxels based on the first pass peak comparison value for the threshold; And D: comparing the times of arrival of said first pass peaks of said pixels and / or voxels in said portion to arrange said two or more portions in relation to one another to obtain a refined model of said human heart, The model may be used particularly to obtain estimates of the left or right atrial volume of the human heart.
