title: Construction of patient-specific surface models from MR images: application to bioelectromagnetism.
abstract: Patient-specific geometric models are needed in many engineering problems. This work reports a novel software tool developed to construct individualized triangulated surface models from MR images. The program consists of three main parts: segmentation, triangulation and registration. The software tool was developed under the UNIX operating system. The application area demonstrated in this work is bioelectromagnetism but the program can be used as well in other engineering problems. The tool has been successfully applied in numerous cases, both for the thorax and the head.
