Performance issues with superconducting cavities and a desire for an enhanced non-invasive view of the interior of a cavity compared to that provided by optical means has led us to inspection using 3-dimensional X-ray tomography. This technique has provided the necessary view of suspected faults in Higher Order Mode couplers. This success naturally leads to determining if x-ray inspection of welds and other potential cavity defects might prove to be helpful during cavity fabrication. Results of x-ray scans from commercial vendors and potential for this technique will be presented.
