Application

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

Registration settings

elastix version: 4.301

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.
