Multimodal Visualization of DTI and fMRI Data Using Illustrative Methods

Designing multimodal visualizations combining anatomical and functional brain data is a demanding task. Jainek et al. [1] applied illustrative rendering techniques to obtain a high-quality representation of the location and characteristic of brain activation areas (derived from MRI and fMRI). Here, we present the integration of DTI data into this system. Reconstructed nerve fibers connecting functional areas with each other and lower brain areas are embedded into the complex rendering pipeline. Further, we enhanced perception of depth and shape by applying silhouettes and dithered halftoning.
