Usage
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.
To create an instance of class vtkMINCImageReader, simply
invoke its constructor as follows
obj = vtkMINCImageReader
Methods
The class vtkMINCImageReader has several methods that can be
used. They are listed below. Note that the documentation is
translated automatically from the VTK sources, and may not
be completely intelligible. When in doubt, consult the VTK
website. In the methods listed below, obj is an instance of
the vtkMINCImageReader class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkMINCImageReader = obj.NewInstance ()
* vtkMINCImageReader = obj.SafeDownCast (vtkObject o)
* obj.SetFileName (string name) - Set the file name.
* string = obj.GetFileExtensions () - Get the name of this
file format.
* string = obj.GetDescriptiveName () - Test whether the
specified file can be read.
* int = obj.CanReadFile (string name) - Test whether the
specified file can be read.
* vtkMatrix4x4 = obj.GetDirectionCosines () - 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.
* double = obj.GetRescaleSlope () - 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.
* double = obj.GetRescaleIntercept () - 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.
* obj.SetRescaleRealValues (int ) - 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.
* obj.RescaleRealValuesOn () - 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.
* obj.RescaleRealValuesOff () - 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.
* int = obj.GetRescaleRealValues () - 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.
* double = obj.GetDataRange () - 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.
* obj.GetDataRange (double range[2]) - 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.
* int = obj.GetNumberOfTimeSteps () - Get the number of time
steps in the file.
* obj.SetTimeStep (int ) - Set the time step to read.
* int = obj.GetTimeStep () - Set the time step to read.
* vtkMINCImageAttributes = obj.GetImageAttributes () - Get
the image attributes, which contain patient information
and other useful metadata.
