Turbo-BrainVoyager (TBV) is a highly optimized, easy to use software package for the real-time analysis and dynamic visualization of functional magnetic resonance imaging data sets. Turbo-BrainVoyager allows to observe the working brain "online" by incrementally computing statistical maps as contrasts of a General Linear Model (GLM). The program also performs real-time pre-processing, including 3D motion correction, spatial Gaussian smoothing and temporal filtering (drift removal). TBV visualizes the data in various formats including a multi-slice (matrix) view, a single (zoomed) slice view and a anatomical volume view. With the help of BrainVoyager QX, the data can also be visualized on 3D data sets in AC-PC and Talairach space as well as on rendered meshes of the cortical sheet. Statistical results as shown as real-time activation movies on the rotatable and zoomable 3D brain models. Regions-Of-Interest (ROIs) can be easily defined using any of the provided visualizations. The raw time courses as well as event-related averaging plots are shown immediately for any of the defined ROIs and are updated as new data becomes available. Besides standard real-time tasks, such as quality assurance, the powerful computational and visualization capabilities of the proram allow advanced applications, such as neurofeedback and neurosurgical monitoring.
