Hi all,

I am looking for a method producing digitally reconstructed radiographs (DRR) from CT volumes and then exporting the DRR as a DICOM file. I have seen basic python scripts that do a similar type of thing and have had no success with the plastimatch module.

Any help would be greatly appreciated!

Thanks in advance
