CogniVis: 3d visualization and navigation module of brain structures

The 3D visualization of brain anatomy plays an important role in the field of medical research, allowing to spatial locate anatomical structures in order to analyze them from different points of view and find the relationships between them. Several research groups have developed tools that allow three-dimensional visualization and navigation on brain models [1]. Amongst the most significant tools, 3Dslicer [2], Brain Voyager [3], and FreeSurfer [4] can be mentioned. However, to the authors’ knowledge there is no a 3D visualization tool capable of working with multiple brain atlas and specifically designed both for researchers and clinicians. In this paper we present Cognivis, a module for 3D neuroimage visualization and navigation designed and implemented as part of a national Spanish project named COGNITIO.
