This thesis deals with the compensation of brain deformations which occur during neurosurgical procedures. Neuroavigation systems have become a very attractive tool in surgical planning and procedure. However, the accuracy and usefulness of such systems are limited in presence of soft-tissue deformations. In neurosurgery, this phenomenon is called ``brain shift''. At present, the compensation of the ``brain shift'' is one of the most important challenge in image-guided neurosurgery. The contribution of this thesis deals with non rigid registration between intraoperative ultrasound images and preoperative magnetic resonance images (MRI). In order to achieve this multimodal non rigid registration, several processes are described in this manus...
