#include <elxAdvancedBSplineTransform.h>
A transform based on the itkAdvancedBSplineTransform.
This transform is a B-spline transformation, commonly used for nonrigid registration.
The parameters used in this class are:
Transform: Select this transform as follows:
(Transform "BSplineTransform")
BSplineTransformSplineOrder: choose a B-spline order 1,2, or 3.
example: (BSplineTransformSplineOrder 3)
Default value: 3 (cubic B-splines).
FinalGridSpacingInVoxels: the grid spacing of the B-spline transform for each dimension.
example: (FinalGridSpacingInVoxels 8.0 8.0 8.0)
If only one argument is given, that factor is used for each dimension. The spacing is not in millimeters, but in "voxel size units". The default is 16.0 in every dimension.
FinalGridSpacingInPhysicalUnits: the grid spacing of the B-spline transform for each dimension.
example: (FinalGridSpacingInPhysicalUnits 8.0 8.0 8.0)
If only one argument is given, that factor is used for each dimension. The spacing is specified in millimeters. If not specified, the FinalGridSpacingInVoxels is used, or the FinalGridSpacing, to compute a FinalGridSpacingInPhysicalUnits. If those are not specified, the default value for FinalGridSpacingInVoxels is used to compute a FinalGridSpacingInPhysicalUnits. If an affine transformation is provided as initial transformation, the control grid will be scaled to cover the fixed image domain in the space defined by the initial transformation.
GridSpacingSchedule: the grid spacing downsampling factors for the B-spline transform for each dimension and each resolution.
example: (GridSpacingSchedule 4.0 4.0 2.0 2.0 1.0 1.0)
Which is an example for a 2D image, using 3 resolutions.
For convenience, you may also specify only one value for each resolution:
example: (GridSpacingSchedule 4.0 2.0 1.0 )
which is equivalent to the example above.
PassiveEdgeWidth: the width of a band of control points at the border of the B-spline coefficient image that should remain passive during optimisation.
Can be specified for each resolution.
example: (PassiveEdgeWidth 0 1 2)
The default is zero for all resolutions. A value of 4 will avoid all deformations at the edge of the image. Make sure that 2*PassiveEdgeWidth < ControlPointGridSize in each dimension.
UseCyclicTransform: use the cyclic version of the B-spline transform which ensures that the B-spline polynomials wrap around in the slowest varying dimension. This is useful for dynamic imaging data in which the motion is assumed to be cyclic, for example in ECG-gated or respiratory gated CTA. For more information see the paper: Nonrigid registration of dynamic medical imaging data using nD+t B-splines and a groupwise optimization approach, C.T. Metz, S. Klein, M. Schaap, T. van Walsum and W.J. Niessen, Medical Image Analysis, in press.
The transform parameters necessary for transformix, additionally defined by this class, are:
GridSize: stores the size of the B-spline grid.
example: (GridSize 16 16 16)
GridIndex: stores the index of the B-spline grid.
example: (GridIndex 0 0 0)
GridSpacing: stores the spacing of the B-spline grid.
example: (GridSpacing 16.0 16.0 16.0)
GridOrigin: stores the origin of the B-spline grid.
example: (GridOrigin 0.0 0.0 0.0)
GridDirection: stores the direction cosines of the B-spline grid.
example: (GridDirection 1.0 0.0 0.0 0.0 1.0 0.0 0.0 0.0 0.1)
BSplineTransformSplineOrder: stores the B-spline order 1,2, or 3.
example: (BSplineTransformSplineOrder 3)
Default value: 3 (cubic B-splines).
UseCyclicTransform: use the cyclic version of the B-spline transform which ensures that the B-spline polynomials wrap around in the slowest varying dimension. This is useful for dynamic imaging data in which the motion is assumed to be cyclic, for example in ECG-gated or respiratory gated CTA. For more information see the paper: Nonrigid registration of dynamic medical imaging data using nD+t B-splines and a groupwise optimization approach, C.T. Metz, S. Klein, M. Schaap, T. van Walsum and W.J. Niessen, Medical Image Analysis, in press.
