Postural instability and gait disorders after subthalamic nucleus deep brain stimulation in Parkinson’s disease: a PET study
Patients with Parkinson’s disease sometimes report postural instability and gait disorders (PIGD) after subthalamic nucleus deep brain stimulation (STN-DBS). Whether this is the direct consequence of DBS or th...

A cognitive engineering framework for the specification of information requirements in medical imaging: application in image-guided neurosurgery
This study proposes a framework coming from cognitive engineering, which makes it possible to define what information content has to be displayed or emphasised from medical imaging, for assisting clinicians ac...

Does subthalamic nucleus stimulation affect the frontal limbic areas? A single-photon emission computed tomography study using a manual anatomical segmentation method
Among the basal ganglia nuclei, the subthalamic nucleus (STN) is considered to play a major role in output modulation. The STN represents a relay of the motor cortico-basal ganglia-thalamo-cortical circuit and...

Validation of MRI/SPECT similarity-based registration methods using realistic simulations of normal and pathological SPECT data
We propose a validation methodology to study the behaviour of SPECT/MRI similarity-based registration methods in normal and pathological conditions. Validation data sets were computed by simulating realistic S...

Modeling Surgical Procedures for Multimodal Image-Guided Neurosurgery
We present a model of surgical procedures that facilitates the management of multimodal information (i.e. anatomical and functional) in the context of multimodal image-guided craniotomies. We suggest that a su...
