Slicer3:LinearRegistrationUseCases

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.

• Results 2008-07-30
  • Using RegisterImages module
  • DO NOT USE DEFAULT PARAMETERS
    • One additional option must be set
    • The difficulty is that fixed image is much larger than the moving image. As a result, too many random samples chosen from the fixed image will fall outside of the moving image, even when they are registered. ITK (correctly or incorrectly, its arguable) throw an exception when this happens.
    • To resolve this, the RegisterImages module has the option to limit the fixed image samples to the initial volume of overlap between the fixed and moving image. This volume of overlap is computed only once, after the initial (center of mass, image centers, landmarks, or none) registration.
    • In the tab, "Advanced registration options" select "Sample from Overlap"
    • See below (left)
  • Output volume looks correct, see below (right)
  • Output transform looks correct
