Neurotracker and Other Medical Applications

Built on the ViSUS framework, NeuroTracker is an application that targets the segmentation of neurons from extremely high resolution Confocal Fluorescence Microscopy brain imagery. NeuroTracker's core data processing uses the ViSUS I/O library to get fast access to brain imaging data combined with multi-resolution topological analysis used to seed the segmentation of neurons. The Voxelscooping image segmentation algorithm is used to extract filamentary structures from the topological seeds. NeuroTracker is based on the ViSUS application framework including ViSUS streaming dataflow and GUI components.

The figure also highlights two additional medical imaging applications. In the center image, an example of the ViSUS framework is used for interactive exploration of an electron microscopy image of a slice of a rabbit retina. In all, this 3D dataset composed of 141 slices is over 5.5 terapixels in size. The image to the right is a 3D data slicing example of the Visible Male6 dataset comprised of over 4.6 billion color voxels.
