• Explore Nipype to see whether we can convert Gifti to VTK or STL, or other compatible format with Slicer (http://www.mit.edu/~satra/nipype-nightly/users/examples/dmri_connectivity.html)
• Discuss the response letter for MICCAI 2014 submissions
• Design Mosaic Viewer outlines
  • 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

Apr 21 - Apr 25

• Make progress to the Mosaic Viewer module. Now it can display and manipulate multiple independent 3D viewers at the same time
• Discuss DTI Challenge preparation. Need to install Evernote and Live Minutes to enhance collaboration
• Next step would be to finalize the Mosaic Viewer by creating a scene view for the it
• 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.
• CMIG multi-channel pattern analysis paper available online http://www.sciencedirect.com/science/article/pii/S0895611114000639

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.
• Run 'Slicer Surface Toolbox' to refine BrainVisa surface. Chcek 'splitting' box in Normals.
• Convert DICOM to FSL (nifty) format.
• Be Invited as one of the NA-MIC tutorial contest judges.
• Attend Junichi's MRI-Robotic experiment

• Test 'DICOM-TO-NIFTI-CONVERTER' matlab toolbox (http://www.mathworks.com/matlabcentral/fileexchange/41874-dicom-to-nifti-converter/content/dicom2nifti.m). However, this toolbox is not usable for our SIEMENS data, because it only work with DICOM files from Phillips Achieva 3T R2.6 with
  • Slice orientation : transverse
  • Patient position : head first
  • Patient orientation: supine
  • Fold-over direction: AP
  • Fat shift direction: P
