    • Load the test data and create the scene views manually
    • Link the scene views to individual 3D mosaic viewers
    • Test one MRI volume in 4 viewers first; then test 4 MRI volumes in 4 viewers; finally test the DTI data

  • Submit the Grants-in-Aid application
  • The original test dataset is a HARDI dataset with 69 gradients plus 4 baselines, and we extracted 30 volumes whose b-values equal to 1000.

• April 28 - May 02
  • Finalize the Mosaic Viewer module.
  • Successfully load and corrected the Brain Visa surface files into Slicer. Next step would be streamline the process. There might be three potential solutions:
    • Build CLI modules (SlicerToBrainVisa Import and Export) to integrate Brain Visa morphologist tools in Slicer. Check NiftyReg extension as an example (https://github.com/spujol/niftyregExtension) and Hello World tutorial to learn how to integrate .cxx plugins (http://www.slicer.org/slicerWiki/images/2/22/ProgrammingIntoSlicer3.6_SoniaPujol.pdf). Note this tutorial might need to be updated to Slicer 4.
    • Build a Python wrapper which point to the Brain Visa executable files and run Brain Visa in Slicer.
    • Write a simple script to 1) convert nhdr to Nifty; 2) filp left / right by changing RAS to LPI coordinate system; 3) run Morphologist pipeline in Brain Visa; 4) load output .ply file in Slicer; and 5) apply 'BrainVisatoSlicer' transform if the coordinate differences were independent to the datasets.
  • Test the DWIConverter module to convert DICOM to nhdr using the datasets '...high-b.raw.gz' dataset and compare the output to '...high-b.nhdr'.
  • New tasks regarding the test dataset:
    • Create the tractography for extracted dataset only using single tensor algorithm
    • Compare the result to that of original dataset using UKF extension
    • Run the DTIPrep extension on both datasets (original and extracted)

• May 05 - May 09
  • Reconstruct the tensors using eigen values and eigen vectors. Slicer could not handle eigen vectors directly, so we ned to calculate the 7 coefficients in the tensor matrix.
  • CMIG multi-channel pattern analysis paper accepted

• May 12 - May 16
  • Run DTIPrep for all the datasets.
  • Clean up and classify all the processed datasets.
  • Send email to Francois checking what are the differences VC and QCed results.
  • Send BrainVisa screenshots to Sonia, describing the sulci recognition problems.
  • Run UKF tractography with 1-6 seeds per voxel, 2 tensors, other parameters by default.

• May 19 - May 23
  • Process the new dataset 'test1'
  • Solve the DTIPrep problems.
    • 1 Why there are 4 baseline images in the original dataset, but only one is left after processing?
    • - All the baselines are merged into one image.
    • 2. How to see the sphere after quality check?
    • - We need to first save the results, and then load the XML to DTIPrep.
    • 3. Why the gradient directions are changed after processing?
    • - This might be a bug, resulted from rounding errors.
    • 4. Why there are holes in the QCed DTI dataset?
    • - We need to reset the parameter 'DTI_bCompute - DTI_baselineThreshold'.

• May 26 - May 30
  • Submit propagation matrix fusion paper to ICARCV 2014.
  • Rerun DTIPrep on 'test1'. After testing with different settings, we found when this parameter is set to less than 50, the holes disappear.

• Jun 02 - Jun 06
  • Run BrainVisa on T1 and T2 registered data, use label map as a mask to filter out the lesion from the generated surface. Try 'Resample Scalar/Vector/DWI Volume' module, set 'Interpolation Type' to ws.
