Create vtk array in the pipeline browser from python

Hi,

I have loaded a 3D image (Dicom stack) into Paraview. From the Python console, I converted this image into a numpy array to perform some segmentation, and then used numpy_to_vtk to get it back into a vtk array (output). How can I create a new object of this vtk array output in the pipeline browser? One solution is to save it as a file but I want to display it in the pipeline browser directly from the console.

Thank you.
