Project Description


Objective Approach and Plan Progress and Next Steps

3D/4D Ophthalmology Image Anaylsis Framework: Continuation of initial January 2017 project by Sungmin Hong:

  • Read 4D hyperspectral data
  • Viewer and interactor for 3D hi-res image data and 4D hyperspectral data
  • Co-registration between 3D hi-res data and 4D hyperspectral data
  • Cell segmentation in 3D hi-res data
  • Statistics of cells (possibly location, size, distribution)
  • Plot of spectra of selected cells or a region-of-interest
  • Review existing modules in 3D Slicer
    • Review existing modules for 4D data viewer, such as, multi-volume viewer extension
    • Try existing segmentation modules in Slicer to see if they can work on SIM data
    • Review existing modules for cell statistics after segmentation
  • Implementation/Integration
    • Implement/integrate 4D hyperspectral data viewer to show image and spectral information.
    • Integrate registration functionality for co-registration between 3D hi-res data and 4D hyperspectral data at image level
    • Explore most recent "Segment Editor" features for cell and organelle segmentation
  • User Manual
    • Create an user manual to comprehend a overview of an extension
  • Manual
  • Registration
    • Basic registration algorithms in Slicer worked well for linear registration between 3D SIM and cropped and dimension reduced 4D LSM data.
    • Automatic detection of corresponding subregions between hires 3D SIM and low-res 4D LSM data may be implemented via autocorrelation.
  • Segmentation
    • GrowCut segmentation worked well for 3D segmentation of organelles of different contrast, e.g. dark Lipofuscin and bright Melanolipofuscin as required by clinical researchers.
    • Cell segmentation/outlining and combination with organelle segmentation can be solved with the Segment Editor features.
  • Hyperspectral Analysis
    • Module to convert 4D LSM data to a series of 3D data compatible to MultiVolume Explorer was implemented at Jan. 2017 project week.
    • With such series of 3D data, MultiVolumeExplorer offers very basic qualitative analysis hyperspectral data by plotting a spectral curve per voxel.
    • Quantitative label statistics by combining 3D segmentation labels with 4D hyperspectral data so far solved via external python script, will need to be added to the multivolume explorer in the future.
