Featurelist BrainVoyager 2000 - List of main program features Overview BrainVoyager is a software package for the analysis and visualization of structural and functional magnetic resonance images. The software was designed for high performance, ease of use and flexible data processing. Basic as well as advanced program features are easily and fully exploited through an intuitive user interface. This allows to compare activated brain regions across different experiments and across different subjects.
Talairach transformation is performed in two steps.
The first step consists in rotating the 3D data set of each subject to be aligned with the stereotaxic axes. In the second step the extreme points of the cerebrum are specified. These points together with the AC and PC coordinates are then used to scale the 3D data sets into the dimensions of the standard brain of the Talairach and Tournaux atlas. Volume rendering is performed with a very fast ray casting algorithm, lightning calculations are based on Phong-shading. Initial polygon meshes serve as the basis for surface finding, cortex inflation and cortex flattening computations.
