![]() ![]() Obviously, however, we’ve just scratched the surface of x-ray tube conditions, so if you have any questions about problem detection, x-ray tubes, or your CT scanner in general, don’t hesitate to contact our dedicated imaging sales experts. With proper care and servicing, your x-ray tube will be working just fine for many years to come. Hopefully this post was of value to your CT system operations and the attention given to your CT x-ray tube. X-ray tube gas: If gas is being emitted by your x-ray tube, this is a big trouble sign, as it means your x-ray tube is no longer a vacuum.Cracks: Vacuum conditions could be affected by fractures in the x-ray tube, so be sure to handle the x-ray tube with care.If you can hear oil being sucked into the tube inset when the tube is turned on, it means you have a punctured tube. Oil: If you see oil in/around the x-ray tube, this could indicate issues with bearings, rotor, or tube housing.This deposit will reduce the effectiveness of the x-ray tube. Look for: tungsten build up deposited on the internal surface of the glass tube window.Keep a sharp eye on your x-ray tube, keeping track of what to look for so that you’ll be able to spot a problem if it arises.How do I know if my x-ray tube needs replaced? Going the safe route of applying current, voltage, and exposure time as appropriate for each individual scan and not exceeding these recommendations is important, as they can greatly extend filament life. The life of the x-ray tube is shortened due to the high tube current causing an evaporation of the tungsten from the filament, which is then deposited onto the glass envelope. ![]() If you frequently go over the recommended current (mA), exposure time, and voltage (kVp) specific to each patient’s examination, you are shortening the life of your CT’s x-ray tube. ![]() As mentioned above, it’s best to consult your manufacturer’s recommendations on the length of your x-ray tube warm-up. When people speak of scanning poems, however, they usually refer to graphic scansion, which involves marking. Some methods of scansion attempt to mark out complex distinctions among sounds and stresses using musical notation or even graphs of sounds waves. Normally, warming up the x-ray tube is done by taking several exposures while waiting 30 seconds – 1 minute between them, but varies due to the variety of CT manufacturers. Scansion involves marking the rhythms of a poem to make the writers technique visible. By warming up your CT system’s x-ray tube, you’re helping to prevent tube damage due to thermal shock. The x-ray tube should almost always be warmed up before use, unless it has been used within the past 2 hours. Prep Before Useįollowing the manufacturer’s recommendations on proper x-ray tube prep is crucial. Let’s take a look at some of the ways x-ray techs can extend the life of their CT system x-ray tubes. Like any piece of machinery, x-ray tubes don’t last forever, but should last for quite a long time if maintained properly by x-ray techs. And inside that CT scanner is an x-ray tube that is vital to the performance of your CT system. Your CT scanner is a vital player in your medical imaging facility. ![]()
