Neurosurgical Datasets

• Neurosurgical Case 1
  • Clinical Case Description
  • Data Description

T1,T2,DWI,DTI :
Segmentation: The file patient1-tumor.nhdr & raw is labelmap which contains the segmented structures: label #1 represents the solid part of the tumor; label #2 represents the cystic part of the tumor.

Control subjects Datasets

Two adult control subject datasets will be available for this challenge. For both subjects we have 10 repetitions of the DTI acquisitions. All scans were done on the same type of scanner at 5 different institutions.

Here are the details of the acquisition parameters:

• 25 directions + 1 B0
• Variable b-value (range between 50 and 1000) - Each diffusion weighted image has a different b value.
• Spacial resolution of 1.97x1.97x2mm
• Image size 96x96x81

File format and naming convention for submission

For each case, the results should be submitted in the following formats: 1) 3D coordinate of the tracts: vtkPolydata ASCII VTK file format; 2) enveloppe of the tracts: ITK-readable Nrrd file format
Naming convention:

• zip archive file: miccaiDTIChallenge_firstAuthorName.zip
• VTK file: firstAuthorName_tract_coordinate.vtk
• Nrrd file: firstAuthorName_tract_enveloppe.nhdr and firstAuthorName_tract_enveloppe.nhdr
• PNG file: firstAuthorName_tract_axialView.png; firstAuthorName_tract_sagittalView.png; firstAuthorName_tract_coronalView.png
