Functieomschrijving

Knowledge of subcortical anatomy is vital in brain surgery. Tractography refers to reconstruction of bundles of axons (‘fibre tracts’) comprising white matter pathways in the brain based on diffusion weighted magnetic resonance imaging. Tractography is hardly used in clinical routine mainly because it is notoriously hard to infer, apprehend and validate tractography results. On top of this, uncertainties related to multiple factors accumulate along the visualization pipeline, hampering its interpretation. Despite this limitations, feasibility studies in the context of temporal lobe as well as brain tumor resection surgery have demonstrated that tractography can, in principle, be incorporated into the daily neurosurgical workflow.

One of the main challenges of this PhD position is to provide tractography accompanied by reliable estimates and insightful visualizations of its ‘limits of accuracy’. In the overall project, the inherent limitations of diffusion tensor imaging (DTI, the model used in the foregoing study) will be handled to cope with regions of complex anatomy. If these goals are met, tractography analysis will become less cumbersome and more reliable, a crucial step towards clinical adoption in the neurosurgical workflow, which is our ultimate goal.

You will be working in a mixed team of mathematicians, computer scientists and clinicians, on a joint project of TUDelft Computer Graphics and Visualization section together with the Department of Neurosurgery of Elisabeth Tweesteden Hospital, the Department of Mathematics & Computer Science of Eindhoven University of Technology. In this common endeavor, your specific focus will be on state-of-the-art visualization and visual analytics strategies to visualize uncertainty in tractography visualization results, and aid the decision making process of the neurosurgeons. You will develop this work in collaboration with the TU Eindhoven partners which will focus on the theory and methodology for tractrography, including quantification and uncertainty propagation, and the Elisabeth Tweesteden Hospital which will develop experimentation and validation in a neurosurgical context.
