Seems there is a reader for that type of file [https://vtk.org/doc/nightly/html/classvtkNrrdReader.html](https://vtk.org/doc/nightly/html/classvtkNrrdReader.html)  
An example similar to what you want ot do is

I might also recommend trying PyVista if you are totally new to VTK: [https://docs.pyvista.org](https://docs.pyvista.org)

It makes reading common file types and plotting them a breeze. Check out the examples: [https://docs.pyvista.org/examples/index.html](https://docs.pyvista.org/examples/index.html)
