Abstract
There are fields of engineering where accurate and personalised data are required; biomedical applications are one such example.
We describe here a general purpose method to create computational meshes based on the analysis and segmentation of raw medical imaging data. The various ingredients are not new: a segmentation method based on deformable contours and a surface and volume mesh adaptation method based on discrete metric specifications; but the challenge that motivated this paper is to put them together in an attempt to design an automatic, easy to use and efficient 3D code.
Résumé
Dans certains domaines du calcul scientifique il est nécessaire de disposer de données précises et personnalisées; les applications biomédicales en sont un bon exemple. Nous présentons ici une méthode générique permettant de générer des maillages de calcul à partir de l'analyse et de la segmentation de données médicales discrètes. Si les divers composants ne sont pas nouveaux: une méthode de segmentation d'images basées sur des contours déformables et des techniques d'adaptation de maillage de surfaces et de volumes basées sur la notion de métrique, le challenge est ici d'assembler ces constituants de manière à obtenir un code de simulation efficace et facile à utiliser.

| What is OpenURL? |
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
