Siemens_E6_DoraEvery MRI scanner depends on its radio frequency power amplifier (RFPA) to provide proper electrical current to the system. If you use a Siemens Symphony MRI, your RFPA is the E6 Dora (part #4753062)- a part that it shares in common with the Siemens Harmony.

Like many components in many different types of imaging equipment, the RFPA is subject to significant stress from its level of output. As a result, RFPA failures can happen suddenly and without much warning. We've already written about some reasons why your E6 Dora might fail, but what we want to share with you today is about how long (in the experience of our parts customers around the world) the typical Dora RFPA lasts and about how much (according to our recent market experience) you can expect to pay to replace one.

Life Expectancy

On average, we've learned to expect an E6 Dora to last anywhere from 2 to 4 years in the field before it fails. Factors like your level of patient traffic, the temperature and humidity of the space you operate your Siemens Symphony in, and the frequency/quality of your preventative maintenance service visits will all play into where on that spectrum your individual Dora will fall. Lower traffic, well-maintained HVAC, and regular service all lend themselves to longer component life in your MRI.


Replacement Cost

Currently, the average costs to replace an E6 Dora are as follows:

New (from the OEM): $25,000

Used: $10,000



Given the popularity of the Siemens Symphony and Harmony scanners, the E6 Dora is not a difficult part to find on the secondary market. Moreover, many of them come from reputable parts suppliers that test their parts and guarantee them. For the next few years at least, there is a strong likelihood that you'll be able to find one used and take advantage of the roughly 60% savings over buying new every time you need a replacement.

If your RFPA has failed, contact us today to have a replacement shipped to you overnight.
