[vtkusers] help with rendering CT series into 3D graphic

[Hp07]

Hi all,

Any help or advise will help me a huge amount. I have been trying to render
a series of CT slices into a 3-D graphic, the window opens and the script
runs with no errors, however the image does not appear in the window.



Please see code below:






import vtk 

 

filepath = r"/Users/hp/Desktop/CT_Slice/"
dcmrder = vtk.vtkDICOMImageReader()
dcmrder.SetDirectoryName(filepath)
dcmrder.Update()
 
  

renderer = vtk.vtkRenderer()
renderwindow = vtk.vtkRenderWindow()
renderwindow.AddRenderer(renderer)
rndrint = vtk.vtkRenderWindowInteractor()
rndrint.SetRenderWindow(renderwindow)
  

renderer.SetBackground(0,0,0)
renderwindow.SetSize(720,720)
 


mc = vtk.vtkMarchingCubes()
mc.SetInputConnection(dcmrder.GetOutputPort())
mc.Update()
 

mapper = vtk.vtkPolyDataMapper()
mapper.SetInputConnection(mc.GetOutputPort())


actor = vtk.vtkActor()
actor.SetMapper(mapper)
    
renderer.AddActor(actor)
rndrint.Initialize()
rndrint.Start()
