USYD:

• Submit the Grants-in-Aid application

April 28 - May 02

DTI Project:

• 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

  • 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
