Detailed Description

Convert DICOM orientation to RAS orientation.

This class will modify an image and its position-and-orientation matrix so that the patient coordinate system follows the conventions of NIFTI and MINC, i.e. the x, y, and z axes will point in the right, anterior, and superior directions respectively. Optionally, the row and column ordering of the image will also be modified so that the row direction preferentially points right or anterior, and the column direction preferentially points superior or anterior.

Member Function Documentation

ComputeMatrix()

void vtkDICOMToRAS::ComputeMatrix ( int  extent[6], double  spacing[3], double  origin[3]  )

protected

Compute the RAS matrix and store it in this->Matrix.

If extent doesn't start at zero, make it so that it does. Also change the origin if RASMatrixHasPosition is Off.

GetRASMatrix()

vtkMatrix4x4* vtkDICOMToRAS::GetRASMatrix ( )

inline

Get a matrix that places the image in RAS coordinates.

This matrix is meant to be used with the output image (unless the method RASToDICOMOn() has been called to reverse the operation of the filter).

IsA()

virtual vtkTypeBool vtkDICOMToRAS::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkThreadedImageAlgorithm.

RequestData()

int vtkDICOMToRAS::RequestData ( vtkInformation *  request, vtkInformationVector **  inputVector, vtkInformationVector *  outputVector  )

protectedvirtual

This is called in response to a REQUEST_DATA request from the executive. Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.

Reimplemented from vtkImageAlgorithm.

RequestInformation()

int vtkDICOMToRAS::RequestInformation ( vtkInformation *  request, vtkInformationVector **  inputVector, vtkInformationVector *  outputVector  )

protectedvirtual

Subclasses can reimplement this method to collect information from their inputs and set information for their outputs.

Reimplemented from vtkImageAlgorithm.

RequestUpdateExtent()

int vtkDICOMToRAS::RequestUpdateExtent ( vtkInformation *  , vtkInformationVector **  , vtkInformationVector *    )

protectedvirtual

Subclasses can reimplement this method to translate the update extent requests from each output port into update extent requests for the input connections.

Reimplemented from vtkImageAlgorithm.

SetAllowColumnReordering()

void vtkDICOMToRAS::SetAllowColumnReordering

(

int

v

)

Allow the columns of the image to be reordered.

The columns can be reordered so that columns with higher indices are further to the right or further anterior. Note that if you turn this option on, then you are implicitly allowing slice reordering to occur as well. If you turn both ColumnReordering and SliceReordering off, then the input data will be directly passed to the output.

SetAllowRowReordering()

void vtkDICOMToRAS::SetAllowRowReordering

(

int

v

)

Allow the rows of the image to be reordered.

The rows can be reordered so that rows with higher indices are further superior or further anterior. Note that if you turn this option on, then you are implicitly allowing slice reordering to occur as well. If you turn both ColumnReordering and SliceReordering off, then the input data will be directly passed to the output.

SetPatientMatrix()

void vtkDICOMToRAS::SetPatientMatrix

(

vtkMatrix4x4 *

matrix

)

Set a matrix that places the image in DICOM patient coords.

This matrix is constructed from the ImageOrientationPatient and ImagePositionPatient meta data attributes. See the SetMemoryRowOrder method for additional information.

SetRASMatrixHasPosition()

void vtkDICOMToRAS::SetRASMatrixHasPosition

(

int

v

)

Set whether the RAS matrix should have a non-zero final column.

By default, the RAS matrix produced by this filter will have a position coordinate in its final column (NIfTI style). Alternatively, this filter can set the final column to zero and use the position to compute a new Origin for the output image. If this option is On, then the Origin of the output image will be (0,0,0), and if it is Off, then the final column of the matrix will be (0,0,0).

ThreadedRequestData()

void vtkDICOMToRAS::ThreadedRequestData ( vtkInformation *  request, vtkInformationVector **  inputVector, vtkInformationVector *  outputVector, vtkImageData ***  inData, vtkImageData **  outData, int  extent[6], int  threadId  )

protectedvirtual

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.

Reimplemented from vtkThreadedImageAlgorithm.

UpdateMatrix()

void vtkDICOMToRAS::UpdateMatrix

(

)

Update the matrix without updating the output data.

This requires that an input has been set, because the origin, spacing, and extent of the input data must be known in order to compute the matrix.
