Abstract: The exemplary embodiments of this invention relate at least in part to a method, apparatus and system to characterize white matter, such as for detecting a presence of a white matter impairment. An exemplary method to characterize white matter includes identifying at least one tract of interest (TOI) in the brain of a subject of interest, the tract of interest having a set of streamtubes representing white matter fibers; determining a set of quantitative tractography metrics associated with the tract of interest, the set of quantitative tractography metrics having a plurality of members; and comparing at least one member of the determined set of quantitative tractography metrics to a corresponding member of a reference set of quantitative tractography metrics, or comparison of one TOI in a single subject or group of subjects and other TOI in the same subject(s).

Abstract: Described is a system, method and computer program product for rendering volumetric multivalued primary data. The system includes a rendering engine having an input coupled to a source of multivalued primary data and an output coupled to a display. The rendering engine includes a data processor for calculating additional data values from the primary data, deriving at least one visual representation from the primary data and the additional data values, and mapping the derived visual representation through transfer functions to hardware primitives for volumetrically rendering the derived visual representation to provide a visualization. The system further includes a user interface for interacting with the visualization.
