Detailed Description

template<class TElastix>
class elastix::RecursiveBSplineTransform< TElastix >

A transform based on the itkRecursiveBSplineTransform.

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 "RecursiveBSplineTransform")

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:

Transform Parameters

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.

Todo: It is unsure what happens when one of the image dimensions has length 1.

overrideprotecteddefault

The destructor.

Member Function Documentation

◆ BeforeAll()

template<class TElastix >

int elastix::RecursiveBSplineTransform< TElastix >::BeforeAll ( )

overridevirtual

Execute stuff before anything else is done:

Initialize the right BSplineTransform.
Initialize the right grid schedule computer.

Reimplemented from elastix::BaseComponent.

◆ BeforeEachResolution()

template<class TElastix >

void elastix::RecursiveBSplineTransform< TElastix >::BeforeEachResolution ( )

overridevirtual

Execute stuff before each new pyramid resolution:

In the first resolution call InitializeTransform().
In next resolutions upsample the B-spline grid if necessary (so, call IncreaseScale())

Reimplemented from elastix::BaseComponent.

◆ BeforeRegistration()

template<class TElastix >

void elastix::RecursiveBSplineTransform< TElastix >::BeforeRegistration ( )

overridevirtual

Execute stuff before the actual registration:

Create an initial B-spline grid.
Create initial registration parameters.
PrecomputeGridInformation Initially, the transform is set to use a 1x1x1 grid, with deformation (0,0,0). In the method BeforeEachResolution() this will be replaced by the right grid size. This seems not logical, but it is required, since the registration class checks if the number of parameters in the transform is equal to the number of parameters in the registration class. This check is done before calling the BeforeEachResolution() methods.

Reimplemented from elastix::BaseComponent.

◆ CreateDerivedTransformParameterMap()

template<class TElastix >

ParameterMapType elastix::RecursiveBSplineTransform< TElastix >::CreateDerivedTransformParameterMap ( ) const

overrideprivatevirtual

Creates a map of the parameters specific for this (derived) transform type.

Implements elastix::TransformBase< TElastix >.

◆ elxClassNameMacro()

template<class TElastix >

elastix::RecursiveBSplineTransform< TElastix >::elxClassNameMacro ( "RecursiveBSplineTransform< TElastix >" )

Name of this class. Use this name in the parameter file to select this specific transform.
example: (Transform "RecursiveBSplineTransform")

◆ GetClassName()

template<class TElastix >

virtual const char * elastix::RecursiveBSplineTransform< TElastix >::GetClassName ( ) const

virtual

Run-time type information (and related methods).

Reimplemented from itk::AdvancedCombinationTransform< TScalarType, NDimensions >.

◆ IncreaseScale()

template<class TElastix >

virtual void elastix::RecursiveBSplineTransform< TElastix >::IncreaseScale ( )

virtual

Method to increase the density of the B-spline grid.

Determine the new B-spline coefficients that describe the current deformation field.
Set these coefficients as InitialParametersOfNextLevel in the registration object. Called by BeforeEachResolution().

◆ InitializeBSplineTransform()

template<class TElastix >

unsigned int elastix::RecursiveBSplineTransform< TElastix >::InitializeBSplineTransform ( )

private

Initialize the right B-spline transform based on the spline order and periodicity.

◆ InitializeTransform()

template<class TElastix >

void elastix::RecursiveBSplineTransform< TElastix >::InitializeTransform ( )

private

Method to set the initial B-spline grid and initialize the parameters (to 0).

Define the initial grid region, origin and spacing, using the precomputed grid information.
Set the initial parameters to zero and set then as InitialParametersOfNextLevel in the registration object. Called by BeforeEachResolution().

◆ ITK_DISALLOW_COPY_AND_MOVE()

template<class TElastix >

elastix::RecursiveBSplineTransform< TElastix >::ITK_DISALLOW_COPY_AND_MOVE ( RecursiveBSplineTransform< TElastix > )

		unsigned int	,
		Superclass2::FixedImageDimension	)

Dimension of the fixed image.

◆ New()

template<class TElastix >

static Pointer elastix::RecursiveBSplineTransform< TElastix >::New ( )

static

◆ PreComputeGridInformation()

template<class TElastix >

virtual void elastix::RecursiveBSplineTransform< TElastix >::PreComputeGridInformation ( )

protectedvirtual

Read user-specified grid spacing and call the itkGridScheduleComputer.

◆ ReadFromFile()

template<class TElastix >

void elastix::RecursiveBSplineTransform< TElastix >::ReadFromFile ( )

overridevirtual

Function to read transform-parameters from a file.

Reimplemented from elastix::TransformBase< TElastix >.

◆ SetOptimizerScales()

template<class TElastix >

virtual void elastix::RecursiveBSplineTransform< TElastix >::SetOptimizerScales ( const unsigned int edgeWidth )

virtual

Set the scales of the edge B-spline coefficients to zero.
