BrainVISA is a software, which embodies an image processing factory. A simple control panel allows the user to trigger some sequences of treatments on series of images. These treatments are performed by calls to command lines provided by different laboratories. These command lines, hence, are the building blocks on which are built the assembly lines of the factory.
BrainVISA is distributed with a toolbox of building blocks dedicated to the segmentation of T1-weighted MR images. The product of the main assembly line made up from this toolbox is the following: grey/white classification for Voxel Based Morphometry, Meshes of each hemisphere surface for visualization purpose, Spherical meshes of each hemisphere white matter surface, a graph of the cortical folds, a labeling of the cortical folds according to a nomenclature of the main sulci:
Anatomist is a visualization software, which main originality is a generic module dedicated to structural data, namely sets of objects linked one another into a graph structure. These objects may be cortical folds inferred from T1 weighted MR data, fiber bundles inferred from MR diffusion weighted data, activated clusters inferred from Statistical Parametric Maps, etc... This module includes a nomenclature control panel, which can drive several brains simultaneously. Anatomist provides also some tools to easily map Statistical Parametric Maps on 3D renderings of the brain, inflated meshes of the cortical surface, etc... Finally, a manual drawing toolbox can be used for various purpose.
Anatomist is the visualisation software used by Brainvisa to show the assembly line results. For this purpose, Brainvisa remote controls Anatomist main menus. Hence, The simplest visualization requests do not require any learning of Anatomist interface. For more advanced usage, however, a glimpse of the possibilities is proposed in Anatomist help pages.
