Project: On-the-Fly Tract Selection: Novel Interaction Paradigms for Diffusion MRI Fiber Visualization
Description
This project aims to design and implement novel interactive selection techniques for diffusion MRI tractography, enabling neuroscientists and clinicians to dissect, segment, and explore white matter fiber tracts in real time. Traditional tractography analysis often relies on static regions of interest (ROIs) or pre-defined anatomical atlases, which can be restrictive when investigating complex or patient-specific connectivity patterns. By developing tools that support direct manipulation of streamlines—such as drag-and-slash cutting, selection boxes, dynamic ROIs, and clipping planes—this work will empower users to iteratively refine tract selection and isolate structures of interest. These interactions will be optimized for responsiveness, allowing fibers to be added, removed, or reshaped on the fly, with immediate visual feedback.
Beyond conventional ROI-based dissection, the project will explore novel interaction paradigms inspired by intuitive gestures and spatial tools. For instance, interactive brushes could "paint" selections across dense fiber bundles, while slicing planes could expose hidden structures through cross-sectional exploration.
