The volume rendering feature in my slicer is not working

My volume rendering option is not working. I am unable to see a 3D model after volume rendering. Kindly check this issue.

It looks like the CT image was acquired with a tilted gantry, which results in a warping transformation. To volume-render a warped volume, the warping transform must be hardened on the volume (see related issue). You can do that in Data module: in the volume’s row, right-click on the transforms column and click Harden transform.
