[vtkusers] 3d reconstruction

[Cameron Burnett]

You can actually read in a DICOM file as a 3D object just using VTK.

vtkDICOMImageReader *dicomReader = vtkDICOMImageReader::New();
  dicomReader->SetDirectoryName( "C:\\dicomfolder\\");

Have a look at Ray Cast Mapping as well (vtkVolumeRayCastMapper). I'm not sure if there is a better way though. With this approach, the image has to reduce its image quality (goes a bit blurry) while you move the camera. Then once you are finished moving around it will return to its original quality.

Alternatively you can read it in using ITK, and then convert it back to VTK. I haven't tried this, so maybe someone can let you know the best way to do it.

Regards,
Cameron.

Subject: [vtkusers] 3d reconstruction







Hi all !

 

Maybe the problem has already been exposed, and I'm sorry if it was.

 

I've managed to made a basic DICOM Viewer. It has 4 views ; 3 views to axial, coronal ans sagittal orientation, and a tridimentionnal view for 3d reconstruction.

 

I'm using igstk::View2D and igstk::View3D.

 

I instantiate a CTImageSpatialObject in which I put the CT Image from the CTImageReader.

Then I put the CTImageSpatialObject into a CTImageSpatialObjectRepresentation and I give it to the igstk::View2D.

 

It's working properly and I can navigate into slides in the three 2D views.

 

My problems is now how to perform a 3D reconstruction of the DICOM and display it in the 3D View.

 

I've search on the net and on the mailing list for some help, but all this is still a little unclear to me.

I just know that ITK and VTK has to be used, but I have no idea of how.

 

If you can help me on that or at least show me the way for begin, I would be very greatfull.

 

Thanks a lot !
