Detailed Description

A reader for MINC files.

MINC is a NetCDF-based medical image file format that was developed at the Montreal Neurological Institute in 1992. This class will read a MINC file into VTK, rearranging the data to match the VTK x, y, and z dimensions, and optionally rescaling real-valued data to VTK_FLOAT if RescaleRealValuesOn() is set. If RescaleRealValues is off, then the data will be stored in its original data type and the GetRescaleSlope(), GetRescaleIntercept() method can be used to retrieve global rescaling parameters. If the original file had a time dimension, the SetTimeStep() method can be used to specify a time step to read. All of the original header information can be accessed though the GetImageAttributes() method.

Member Function Documentation

virtual const char* vtkMINCImageReader::GetClassName (  )  [virtual]

Reimplemented from vtkImageReader2.

static int vtkMINCImageReader::IsTypeOf ( const char *  name  )  [static]

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

Reimplemented from vtkImageReader2.

virtual int vtkMINCImageReader::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkImageReader2.

static vtkMINCImageReader* vtkMINCImageReader::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkImageReader2.

static vtkMINCImageReader* vtkMINCImageReader::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkImageReader2.

virtual void vtkMINCImageReader::PrintSelf ( ostream &  os,
vtkIndent  indent 
) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkImageReader2.

virtual void vtkMINCImageReader::SetFileName ( const char *  name  )  [virtual]

Set the file name.

Reimplemented from vtkImageReader2.

virtual const char* vtkMINCImageReader::GetFileExtensions (  )  [inline, virtual]

Get the entension for this file format.

Reimplemented from vtkImageReader2.

Definition at line 99 of file vtkMINCImageReader.h.

virtual const char* vtkMINCImageReader::GetDescriptiveName (  )  [inline, virtual]

Get the name of this file format.

Reimplemented from vtkImageReader2.

Definition at line 105 of file vtkMINCImageReader.h.

virtual int vtkMINCImageReader::CanReadFile ( const char *  name  )  [virtual]

Test whether the specified file can be read.

virtual vtkMatrix4x4* vtkMINCImageReader::GetDirectionCosines (  )  [virtual]

Get a matrix that describes the orientation of the data. The three columns of the matrix are the direction cosines for the x, y and z dimensions respectively.

virtual double vtkMINCImageReader::GetRescaleSlope (  )  [virtual]

Get the slope and intercept for rescaling the scalar values to real data values. To convert scalar values to real values, use the equation y = x*RescaleSlope + RescaleIntercept.

virtual double vtkMINCImageReader::GetRescaleIntercept (  )  [virtual]

Get the slope and intercept for rescaling the scalar values to real data values. To convert scalar values to real values, use the equation y = x*RescaleSlope + RescaleIntercept.

virtual void vtkMINCImageReader::SetRescaleRealValues ( int   )  [virtual]

Rescale real data values to float. If this is done, the RescaleSlope and RescaleIntercept will be set to 1 and 0 respectively. This is off by default.

virtual void vtkMINCImageReader::RescaleRealValuesOn (  )  [virtual]

Rescale real data values to float. If this is done, the RescaleSlope and RescaleIntercept will be set to 1 and 0 respectively. This is off by default.

virtual void vtkMINCImageReader::RescaleRealValuesOff (  )  [virtual]

Rescale real data values to float. If this is done, the RescaleSlope and RescaleIntercept will be set to 1 and 0 respectively. This is off by default.

virtual int vtkMINCImageReader::GetRescaleRealValues (  )  [virtual]

Rescale real data values to float. If this is done, the RescaleSlope and RescaleIntercept will be set to 1 and 0 respectively. This is off by default.

virtual double* vtkMINCImageReader::GetDataRange (  )  [virtual]

Get the scalar range of the output from the information in the file header. This is more efficient that computing the scalar range, but in some cases the MINC file stores an incorrect valid_range and the DataRange will be incorrect.

virtual void vtkMINCImageReader::GetDataRange ( double  range[2]  )  [inline, virtual]

Get the scalar range of the output from the information in the file header. This is more efficient that computing the scalar range, but in some cases the MINC file stores an incorrect valid_range and the DataRange will be incorrect.
