Multiple views simplify the task of localizing these parts of the brain. Complementary information is brought into the visualization by Magic Mirrors in order to enhance the comprehensive view of the multimodal arrangement of volume data sets. Top, selected MRI slices are merged with functional data by pixel interleaving. Middle, the maximum intensities of the data are projected onto axial, coronal and sagital planes bearing brain outlines and millimetric Talairach coordinates. Bottom, the maximum data intensities are projected along the line of sight onto the cortical surface.
Different problems arise when using direct volume rendering.
Left, very low opacity allows deeper structures to be visualized. However, it is hard to tell, where the foci reside exactly.
