Hello ,<br>
<br>
Kindly pardon my question here. I know this has been asked several times in<br>
the past and yet ask it again. I am trying to read dicom files and view it<br>
interactively using windowInteractor. My ulitmate goal is to be able to pump<br>
this image through the volume rendering algorithm.<br>
<br>
However, when I run the following script (python script), I only get to see<br>
one slice as opposed to the entire volume. Could<br>
someone please help me trouble shoot this.<br>
<br>
<br>
#! /usr/bin/env python<br>
<br>
import vtk as v<br>
from vtk.libvtkGraphicsPython import*<br>
from vtk.libvtkCommonPython import*<br>
<br>
reader=v.vtkDICOMImageReader()<br>
reader.SetDirectoryName('$DICOM DIR')<br>
reader.Update()<br>
<br>
slope=1<br>
shift=0<br>
<br>
shifter=v.vtkImageShiftScale()<br>
shifter.SetShift(shift)<br>
shifter.SetScale(slope)<br>
shifter.SetOutputScalarTypeToUnsignedChar()<br>
shifter.SetInput(reader.GetOutput())<br>
shifter.Update()<br>
<br>
voxeldata=v.vtkImageData()<br>
voxeldata=shifter.GetOutput()<br>
voxeldata.AllocateScalars()<br>
<br>
<br>
actor=v.vtkImageActor()<br>
actor.SetInput(voxeldata)<br>
<br>
ren=v.vtkRenderer()<br>
renWin = v.vtkRenderWindow()<br>
renWin.AddRenderer(ren)<br>
renWin.SetSize(300,300)<br>
<br>
iren = v.vtkRenderWindowInteractor()<br>
iren.SetRenderWindow(renWin)<br>
ren.AddActor(actor)<br>
iren.Initialize()<br>
iren.Start()<br>
<br>
Thank you<br>
Sincerely,<br>
Ankit<br>
