What image extension does Volview accept? I have **.mhd** images.  
But I get an error that it cannot read the image.  
What format should my images have to be able to see them?

I’m not a VolView user, but here is the section of the documentation that [discusses input file formats](https://kitware.github.io/VolView/doc/loading_data.html#File-formats).
