Image data

  • 3D chest CT
  • Lung
  • 20 scans
  • Voxel size mostly 0.7x0.7x~0.7 mm, four scans with thicker slices 1.25, 1.5, 2, 2.5 mm.
  • Dimension: on average about 400 x 300 x 350

Screen shots:




Registration of intra-patient pulmonary CT scans for the EMPIRE10 challenge at MICCAI. Sometimes sheep lungs.

For more information visit the EMPIRE10 website.

The results of the challenge can be found here.

Registration settings

elastix version: 4.301

Parameter files used at the workshop:

Parameter files for the smoothed version submitted after the workshop:

Command line calls:

elastix -f scans/x_Fixed.mhd  -m scans/x_Moving.mhd  -p parameters.Par0011.affine.txt   -out outDir1_x

elastix -f scans/x_Fixed2.mhd -m scans/x_Moving2.mhd -p parameters.Par0011.bspline1.txt -out outDir2_x
    -t0 outDir1_x/TransformParameters.0.txt

elastix -f scans/x_Fixed2.mhd -m scans/x_Moving2.mhd -p parameters.Par0011.bspline2.txt -out outDir3_x
    -t0 outDir2_x/TransformParameters.0.txt -fMask lungMasks/x_Fixed.mhd

where x refers to the patient number (01 - 20), and Fixed2 and Moving2 to slightly pre-processed versions of the fixed and moving image.
