In this paper, we present a new approach for segmenting regions of bone in MRI volumes using a deformable model. Our method takes into account the partial volume effects that occur with MRI data, thus permitting a precise segmentation of these bone regions. Partial volume is estimated, in a narrow band around the deformable model, at each iteration of the propagation of the model. Segmentation of the skull in medical imagery is an important stage in applications that require the construction of realistic models of the head. Such models are used, for example, to simulate the behavior of electro-magnetic fields in the head and to model the electrical activity of the cortex in EEG and MEG data.
