How To Tell If Your CT Tube Is About To Fail

Signs_of_Tube_Failure.jpgAt the heart of every CT scanner is its X-ray tube. More so than any other component, keeping careful tabs on the functioning of the CT tube can mitigate the cost of owning and operating a CT system. Unfortunately, some people only start thinking about the remaining lifespan of their X-ray tube after the system has been installed and in use for several years. This can mean that some damage has already been done.

On the bright side, there are early warning signs that CT users can watch out for to identify when CT tube help is needed. Here are a few things to keep in mind:

Loud Tube Bearing Noise

During scanning, the anode of the X-ray tube is constantly spinning. If the bearings inside the tube housing are wearing out they’ll become noisy and the user will hear a “humming” sound.

Arcing That Interrupts Scanning

A certain small amount of electrical arcing in the tube is actually tolerated by your CT scanner. If the arcing is getting out of control, however, it may interrupt you mid-scan. Be on the lookout for arc-related error messages in your log. This could be a precursor to more frequent interruptions.

Immediate Shutdown With Arc Error

The immediacy of this error lets you know that the arcing is happening consistently. This is more likely to happen with a cold tube that has not been run through its warm-up sequence, so be sure to allow time for warm-up at the beginning of each scanning schedule.

Change In Tube Cooling Delay Frequency

If your scanner is reaching the upper limits of its operating temperature, the system will stop between techniques to give the tube a break. If the breaks are getting consistently longer, you may have a problem.

What You Should Do

If you are experiencing any of these warning signs, it is a good idea to call your imaging equipment service organization and have your CT scanner checked out. These issues may be in their beginning stages and can be circumvented before too much damage is done to the tube. Other times, the news is not so good and the best a field engineer can do is clear error messages and run preventative measures to keep your existing tube up and running a tiny bit longer while you search for a new solution.
