You need to create a vtkMRMLScalarVolumeNode as shown [here](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Create_a_new_volume). I’m not sure how to set the pixel data in vtkImageData from a QByteArray but @pieper did something similar in the past so maybe he can help.

A much simpler approach is to write the byte array to a file, create a text header file (e.g., a [NRRD image file header](https://discourse.slicer.org/t/load-vol-file-into-3d-slicer-from-morita-machine/4815/5)) and read the header file into Slicer using `slicer.util.loadVolume("path/to/something.nhdr")`.
