Dear Samuele,
 good that you found a solution that fits your purpose.
You should place the writer after the call to Execute(). Also, self.vmtkImageWriter.Input should be the set to
self.vmtkImageWriter.Input = self.vmtkImageVOISelector.Image
This way it should work.
Regards

Luca

Dear Luca,

actually what you suggested is not exactly what I wanted to do. I solved my problem like this:

   def VOI(self, input_filename, output_filename):

self.vmtkImageVOISelector = vmtkimagevoiselector.vmtkImageVOISelector()
self.vmtkImageVOISelector.Image = self.vmtkImageViewer.Image
self.vmtkImageVOISelector.vmtkRenderer = self.vmtkImageViewer.vmtkRenderer
self.vmtkImageVOISelector.Interactive = 1

self.vmtkImageViewer.PlaneWidgetX.Off()
self.vmtkImageViewer.PlaneWidgetY.Off()
self.vmtkImageViewer.PlaneWidgetZ.Off()

# self.vmtkImageWriter = vmtkimagewriter.vmtkImageWriter()
# self.vmtkImageWriter.OutputFileName = self.subdir + "/" + output_filename + "_VoI.vti"
# self.vmtkImageWriter.Input = input_filename + ".vti"
# self.vmtkImageWriter.OutputFileName = output_filename + "_VoI.vti"
# print "Il file di output e': " + self.vmtkImageWriter.OutputFileName
# self.vmtkImageWriter.Execute()

print "Press i to activate the volume selector and q (twice) when you have done"
print " "

self.vmtkImageVOISelector.Execute()

So that when I select a VoI the "old" image (that I had from the vmtkimageviewer command) disappers.

The problem I am facing now, instead, is  on how to use the vmtkimagewriter function...

The commented line do not work...

Could anyone help with this?

Thanks a lot,

Samuele.

Dear Samuele,
you should call the DeepCopy only after
self.vmtkImageVOISelector.Execute()
since only after that call you'll have the new VOI volume ready to render.

Dear Luca,

I think that 2nd option is the way.

Actually, I do have to fix the code, but I am following that path.

What do you think about doing:

 ## function that allows us to view the .vti image just created
 #  @param self The object pointer
 #  @param input_filename The name of the .vti file we want to view (inserted from the user)
 def imageviewer(self, input_filename):

self.vmtkImageReader = vmtkimagereader.vmtkImageReader()
self.vmtkImageReader.InputFileName = self.subdir + "/" + input_filename + ".vti"
self.vmtkImageReader.Execute()
self.vmtkImageViewer = vmtkimageviewer.vmtkImageViewer()
self.vmtkImageViewer.Image = self.vmtkImageReader.Image
self.vmtkImageViewer.vmtkRenderer = self.vmtkRenderer
print " "
print " "
print "Press q to re-activate the interaction with the GUI"
print " "
self.vmtkImageViewer.Execute()

 def DICOMinteract(self):
     if self.vmtkImageViewer:
self.vmtkImageViewer.Execute()
else:
print "Image not loaded yet"

 ## function that allows us to select a volume of interest
 #  @param self The object pointer
 #  @param input_filename The name of the .vti file we want to use
 #  @param output_filename The name we want to give to the output file (after having selected a VoI)
 def VOI(self, input_filename, output_filename):

     # self.vmtk.vmtkImageViewer.vmtkRenderer.RemoveAllViewProps()
     # vmtkImageReader = vmtkimagereader.vmtkImageReader()
     # vmtkImageReader.InputFileName = self.subdir + "/" + input_filename + ".vti"
     # vmtkImageReader.Execute()
self.vmtkImageVOISelector = vmtkimagevoiselector.vmtkImageVOISelector()

self.vmtkImageViewer.Image.DeepCopy(self.vmtkImageVOISelector.Image)

#self.vmtkImageVOISelector.Image = self.vmtkImageReader.Image

self.vmtkImageVOISelector.vmtkRenderer = self.vmtkRenderer
print "Presso i to activate the volume selector and q (twice) when you have done"
print " "
self.vmtkImageVOISelector.Execute()

It what I did, what you meant?

Thanks a lot,

Samuele

Hi Samuele,
to replace the original image with the new image, just assign the new image
to vmtkImageViewer.Image, for example
self.vmtkImageViewer.Image = voiImage
and then call
vmtkImageViewer.Execute()

Alternatively, if it's ok for you to lose the original image and get rid of it for memory efficiency purposes,
just do
self.vmtkImageViewer.Image.DeepCopy(voiImage)

Let me know if either of the above solve your problem.

Regards

Luca

Dear all,

I have a question for you. I am trying to use vmtk in a GUI that I created. After having used the vmtkimageviewer I would like to do the selection of a volume of interest.

The very problem is that when I press the "Select VoI" button I got in my window 2 images (better, two copies of the same image)...

The code is the following:

 ## function that allows us to view the .vti image just created
 #  @param self The object pointer
 #  @param input_filename The name of the .vti file we want to view (inserted from the user)
 def imageviewer(self, input_filename):

self.vmtkImageReader = vmtkimagereader.vmtkImageReader()
self.vmtkImageReader.InputFileName = self.subdir + "/" + input_filename + ".vti"
self.vmtkImageReader.Execute()
self.vmtkImageViewer = vmtkimageviewer.vmtkImageViewer()
self.vmtkImageViewer.Image = self.vmtkImageReader.Image
self.vmtkImageViewer.vmtkRenderer = self.vmtkRenderer
print " "
print " "
print "Press q to re-activate the interaction with the GUI"
print " "
self.vmtkImageViewer.Execute()

 def DICOMinteract(self):
     if self.vmtkImageViewer:
self.vmtkImageViewer.Execute()
else:
print "Image not loaded yet"

 ## function that allows us to select a volume of interest
 #  @param self The object pointer
 #  @param input_filename The name of the .vti file we want to use
 #  @param output_filename The name we want to give to the output file (after having selected a VoI)
 def VOI(self, input_filename, output_filename):

     # vmtkImageReader = vmtkimagereader.vmtkImageReader()
     # vmtkImageReader.InputFileName = self.subdir + "/" + input_filename + ".vti"
     # vmtkImageReader.Execute()
self.vmtkImageVOISelector = vmtkimagevoiselector.vmtkImageVOISelector()
self.vmtkImageVOISelector.Image = self.vmtkImageReader.Image
self.vmtkImageVOISelector.vmtkRenderer = self.vmtkRenderer
print "Presso i to activate the volume selector and q (twice) when you have done"
print " "
self.vmtkImageVOISelector.Execute()

Well, the question is: how can I remove the former image?

Thanks a lot,

Samuele
