There are several conditions that can cause image/ring artifacts. More often than not, artifacts are indicative of a DAS (Data Acquisition System) malfunction, not a problem with the tube. One quick and easy solution is to check the tube alignment. Beam cut-off or lower tube output occurs when a tube is out of specification. Refer to the OEM guidelines for proper tube installation and follow the alignment procedures.

Arcing, caused by instability in mA current, wreaks havoc on tube performance and your high voltage system. Check mA using a scope and calibrate according to the OEM specifications. The OEM service manual lists mA tolerance levels. Other checkpoints for arcing are the HV cables, wells, and high voltage/filament tanks.
