A 3-D View of the Brain

Researchers at Thomas Jefferson University Hospital, in Philadelphia, have developed software that integrates data from multiple imaging technologies to create an interactive 3-D map of the brain. The enhanced visualization gives neurosurgeons a much clearer picture of the spatial relationship of a patient's brain structures than is possible with any single imaging methods. In doing so, it could serve as an advanced guide for surgical procedures, such as brain-tumor removal and epilepsy surgery. The new imaging software collates data from different types of brain-imaging methods, including conventional magnetic resonance imaging (MRI), functional MRI (fMRI), and diffusion-tensor imaging (DTI). The MRI gives details on the anatomy, fMRI provides information on the activated areas of the brain, and DTI provides images of the network of nerve fibers connecting different brain areas. The fusion of these different images produces a 3-D display that surgeons can manipulate: they can navigate through the images at different orientations, virtually slice the brain in different sections, and zoom in on specific sections. for more information about this news: http://www.technologyreview.com/Biotech/19140/page1/
