• Applications
  • 3DVIEWNIX is a transportable software system with state of the art capabilities for visualizing, manipulating, and analyzing multi-dimensional multimodality image information.  3DVIEWNIX was designed to promote widespread use of 3D imaging and allow end users to set up an inexpensive state of the art imaging system.  This tool was also designed to promote cooperative research (technical and applied) in 3D imaging.  3DVIEWNIX was designed to run on UNIX machines under X-Windows.  This software is application independent and can handle rigid, non-rigid, static, and dynamic objects and object assemblies.  3DVIEWNIX is an open software system distributed with source code when the software is purchased.  3DVIEWNIX has several built-in operations including preprocessing, visualization, manipulation, and analysis.  There is ongoing work to extend the capabilities of 3DVIEWNIX in the future.  Clinical projects currently using 3DVIEWNIX include lesion detection from MIR brain images in Multiple Sclerosis patients, segmentation of fuzzily defined objects, joint kinematics, vessel imaging and detection of abnormal pathology in MR angiograms, and virtual reality applications in medical imaging.  In 1994, 3DVIEWNIX was named "Top 10 Graphics Software Product of the Year" by IEEE Computer Graphics and Applications.
  • Functions:
    • Visualization:
      • Slice:
        • Sophisticated form of slice display
        • Multiple input volumes of any dimensionality can be handled simultaneously
        • Multiple color maps
      • Surface Rendering:
        • Multitudes of methods
        • Multiple objects with translucency and color
        • Based on the notion of a structure system: A structure system may be a collection of static objects, dynamic rigid objects, dynamic non-rigid objects or any of these coming from multiple modalities
        • Viewing properties of objects can be changed independently.
      • Volume Rendering: Interactive rendering, Interactive color modification, Interactive measurement of fuzzy surfaces.
      • Manipulation:
        • One of the most sophisticated set of operations in 3DVIEWNIX
        • A variety of complex operations including cut away, reflect, separate, move, surface marking, measure, animation
      • Analysis:
        • Measurement:
          • A variety of image intensity-based measurements such as density profile, time density curves, region-of-interest statistics and their variation with time.
        • Registration:
          • Based on matching homologous features - points, curves, entire surfaces
          • For merging information from multiple modalities
          • For motion description and analysis.
        • Motion Analysis:
          • Rigid object assemblies
          • Animation of motion and its quantification
          • Comparison of motion of two assemblies of objects such as two joints
          • Relationship between moving surfaces
      • Preprocessing:
        • Volume-of-Interest: To specify subset of the n-dimensional (nD) volume image
        • Interpolation: To create isotropically sampled data of lower or higher resolution than input
        • Filtering:
          • A variety of forms of enhancing and smoothing filters
          • Used for filtering surfaces, for normal estimation, for interpolation, and volume rendering.
        • Thresholding: Multiple intervals can be specified
        • Segmentation:
          • 2-feature cluster partitioning
          • Quick gesture-controlled (user-guided) boundary segmentation.
        • Classification:
          • 1-feature multiple material classification for opacity assignment
          • 2-feature multiple material classification for opacity assignment.
        • Boundary Formation:
          • Connected, oriented, closed 3D surfaces are formed
          • Surfaces may have any resolution.
        • Image Algebra:
          • Image addition, subtraction, logical operation
      • Additional Features
        • Analysis: measurement, registration and motion analyses
