Home < Slicer3:Registration

Slicer 3 includes linear and nonlinear registration tools built as command line modules. On this page we are working to collect a variety of example data sets which test the boundary cases in order to optimize the registration performance and accuracy.


See also additional use cases collected for nonlinear registration optimization.



T2 to FA Affine Registration

Results using slicer2
Results using slicer3 as of 2008-04-07


  • Reference 'Gold Standard'
    • Slicer2 calculation using Mattes MI Affine (also uses ITK implementation)
    • Result transform:
   0.998582 0.0548244 0.00874164 1.86596 
   -0.051956 0.957673 0.0339914 -12.8223

   0 0 0 1


  • Software
    • Slicer3 svn trunk 2008-04-07
  • Parameters
    • Defaults
  • Method
    • Use T2 as fixed, FA as moving
    • Create new output transform and output volume (no input transform)
    • In data module drag FA volume under the newly calculated transform
    • In Transform Module select the output transform and click Invert
  • Results 2008-04-07
    • Output volume appears to be all 0
    • Output transform looks correct, see image to the right.
