Parkinson patients sometimes develop sudden insults with strongly disabling tremor. It has been found that electrical stimulation of the nucleus subthalamicus can strongly reduce the insult. However, the precise targeting of this tiny nucleus in the deep brain is difficult and has high risks. The navigation can be assisted by inter-operative MRI (with a mobile MRI in the operating room), optimal path planning by evading blood vessels and ventricles in the penetration path, and by integrated interactive visualisation of the available multi-modality 3D information, such as pre-operative MRI, functional MRI and Diffusion Tensor Imaging tractography. The 3D visualization of the huge datasets is performed in real-time with modern graphics (‘computer game’-) cards.
