[vtkusers] about vtkImageData

[Lic. José M. Rodriguez Bacallao]

as I said before, until now, I have been using vtkGDCMImageReader but
now I wan't to use pydicom, this is how I read the image with pydicom:

import dicom
dataset = dicom.read_file('./path/to/file.dcm')
pixel_array = ds.pixel_array #numpy array
pixel_data = ds.PixelData #string of bytes

question is: How do I visualize any of these with vtk to see a dicom image?
