Straton Z CT Tube Lifespan and Cost

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 and is coincidentally the most expensive part to replace.

If you're scanning with a Siemens Sensation 64, you're using Siemens' proprietary Straton Z tube.

Because Straton Z tubes are proprietary to Siemens and there are no alternatives from other tube manufacturers. This keeps the price on the higher side compared to other tubes. When you can find a used Straton, however, you can save a substantial amount. 

Below, we'll share with you the average lifespan, average replacement cost, part number of the Straton Z CT tube, and how you can order a 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.

In some instances, a Straton Z tube can last up to 500,000+ scan seconds.

If a facility scans a middle-range patient volume, this translates to approximately 2-3 years. 

Straton Z Average Cost

Straton tubes are proprietary to Siemens and there are no alternatives from other tube manufacturers. This keeps the price on the higher side compared to other tubes. When you can find a used Straton, however, you can save a substantial amount. 

Used Straton Z tubes (with a quarter of their life in usage) average between $75,000 and $90,000.

A tube with very low usage will average between $110,000 and $125,000.

The Takeaway

If your Straton Z is approaching the 350,000 scan-second mark or experiencing other warning signs of a tube failure, it's a good idea to begin looking for your next replacement.

Availability can sometimes be a challenge, given Straton Z's proprietary nature, but when used units are found, there are a lot of costs to be saved.
