Abstract

We have developed semi-automatic methods for reconstructing boundary element thorax models from magnetic resonance (MR) data of the heart. The thorax, the lungs and the heart were segmented from the MR images, and then triangulated. A registration method was applied to convert the magnetic resonance coordinates to the frame of the MCG recordings, and to represent the non-invasive MCG localization results on the MR images
