Influence of Torso Model Accuracy on the Noninvasive Localization of Heart Pathologies
Popis výsledku v původním jazyce
The influence of the fidelity of an inhomogeneous torso model on the noninvasive inverse localization of selected heart pathologies. It was supposed that the extent of the pathology is small enough to be represented by a single dipole. In the simulationstudy the accuracy of localization of an ischemic lesion was investigated. 18 different ischemic lesions in the ventricles were modeled and corresponding surface ECGs were simulated in 7 CT-based realistic torso models. Position of each lesion represented by a single dipole was then searched by an inverse solution using different approximations of the torso and heart. If the original realistic CT-based torso and heart model was used the mean error of the lesion localization was 0.7 cm. When a common torso and heart model were used this error reached 3.4 cm and decreased to 1.0 cm if the common torso model was adjusted to the realistic shape using 10 patient specific anatomical parameters and properly formed and rotated heart model was u
