Construction of the geometrical-conductivity human chest model in simulation of the cardiac electrical field.
In this article the problem of the construction of the geometrical-conductivity model of a human chest in a computer simulation of the cardiac electrical field, applying image diagnostic data (CT, conventional radiography and 2D projections of a torso) is presented. On the basis of these data parameters are defined which allow the determination of locations and sizes of significant chest organs. Calculations and comparison of the values of these parameters for CT and radiographic data of the example patient, using image processing methods, have been carried out. A numerical experiment has been performed to determine the epicardial maps, applying two geometrical-conductivity models of the individual patient based on CT (accurate) and radiographic (approximate) image data, respectively. The credibility of the results obtained is discussed.
