When it comes to service and maintenance for a CT scanner, the most important item to keep tabs on is the tube. On any CT, the tube is a part that will need to be replaced periodically .Coincidentally, it's also one of the most expensive to replace.
If you're scanning with a Siemens Sensation 64, you're using Siemens' proprietary Straton Z tube. Below, we'll share with you the average lifespan, average replacement cost, and part number of the Straton Z CT tube.
Straton Z Average Life Expectancy
In the experience of our field service team and the CT users we interact with every day, a Straton Z tube typically lasts around 350,000 scan seconds, with some instances of tubes lasting up to 500,000+. If a facility scans a middle-range patient volume, this translates to approximately 2-3 years.
Straton tubes are proprietary to Siemens and there are no alternatives from other tube manufacturers, keeping the price on the higher side compared to other tubes. When you can find a used Straton, however, you can save a substantial amount. Right now, used Straton Z tubes average between $75,000 and $90,000 for a tube that has seen approximately a quarter of its life in usage and $110,000 and $125,000 for a tube with very low usage.
The part number for a Straton Z tube is: 7737807
If your Straton Z is approaching the 350,000 scan second mark or experiencing other warning signs of tube failure, it's a good idea to begin looking for your next replacement. Availability can sometimes be a challenge, given the Straton's proprietary nature, but when used units are found, there's a lot of cost to be saved.
