Debug and Repair of MRI Coils Training

February 06, 2019 08:41

I would like to learn how to debug and repair the electronics in MRI patient coils. I don't know where to start or find information related to diagnosing them. I could use procedures, papers, schematics, videos, training seminars and teachers, etc. I'm will purchase the necessary equipment to get going. I have an electronics background.
You may direct your advise to:

Thanks,

Mike Manning

Hi Richard, thanks for reaching out to me today. I have already ordered the Text you mentioned and I'm looking into getting a network analyzer. Yes I'm still in Charlotte NC. May I contact you at a later time if I have questions about debugging coils?
Thanks,
Mike

Pinnacle Health Services can train you but we can also fix most coils for under $2k so it may not be worth your time. Reach out to me to discuss.

Hi Jody, thank you for reviewing my post on DotMed. Over the next couple of days I'm reviewing the information I have and will decide on how to proceed. Your information is valuable, and I'm keeping your services in mind.
Thanks,

Mike Manning

There are a couple of things I learned. One is the purchase of this text book. Here is a link.
https://books.google.com/books/about/RF_Coils_for_MRI.html?id=RHGX79V2jVgC&printsec=frontcover&source=kp_read_button#v=onepage&q&f=false
The other is I purchased an analyzer,
6015-5251 Bravo MRI II Dual Port with BNC Kit & Hard Case - $2795 Here is a link to their website.
http://www.aeatechnology.com/mri-bravo
Hopefully this helps, we're still in the early stages.

I would recommend a bit of caution with the Bravo analyzer, it's been awhile since I've checked on it but I believe the output power level will exceed some of the passive decoupling circuits and certainly was above the input power for preamps. It's why I recommend an analyzer similar to a Keysight E5061B that has a variable attenuator.

Hi Richard, thank you for that input. It makes sense that some of the signal levels are very low power and we didn't consider that. Only that the Bravo was advertised as a tester for MRI coils for systems in the range of 0.1T - 3.0T.
We were wondering if it would be smarter to make a loop antenna and use it instead of connecting the Via Bravo directly to the coils.
