Max. SAR per second - Whole Body (Normal, 1st Controlled, 2nd Control)
Hello fellow imaging technologists & professionals!

I'm involved in the development of a new type of cardiovascular medical device.

This device employs MRI technology/scans to power, guide, and control the medical devices and their active elements.

I conducted some research into the following question, "How much x-ray energy is allowed within a human every sec from a MRI machine?"

With regards to SAR rates, I understand that these are the upper-limits for the various settings for a full-body scan:

Normal setting: Whole body SAR - 2

1st Level Controlled: Whole body SAR - 4

2nd Level Controlled: Whole body SAR - >4

Would you agree with these calculations that I performed, and if not, why? And what would be a better way to calculate this?

For WHOLE BODY SAR:

-SO IF IN NORMAL MODE FOR MRI, THE MAX. ALLOWABLE SAR IS "2" OVER A 6 MIN. PERIOD, THEN
-6 MIN. = 360 SECONDS
-2 / 360 = 0.00555

FOR 1ST LEVEL CONTROLLED:

-SO IF IN 1ST LEVEL CONTROLLED FOR MRI, THE MAX. ALLOWABLE SAR IS "4" OVER A 6 MIN. PERIOD, THEN
-6 MIN. = 360 SECONDS
-4/ 360 = 0.01111

Other questions -- What is the difference between normal setting, 1st conrolled and 2nd controlled?

What is the clinical purpose of these various settings?

Any insights that you would be willing to share in regards to the above would be greatly appreciated!

I was trained and registred as a diagnostic echocardiographer, specializing in cardiovascular ultrasound, therefore I need help with MRI information/specifications. I am now focusing on the medical device field, but this technology/device happens to be highly dependent on MRI technology.


Any help from the group would be greatly appreciated!!

Thanks & regards,


Clifford Thornton

Experiences with Artroscan C
Is there anyone who have experiences with the Artroscan C by Esaote. My hospital is seriously considering to purchase one or one similar to this model.
There is a flexible coil with this machine which might be used to image the hip the representative said. I have serious doubts how a small flex coil can image an adult hip.
If there is anyone who have experience with such a machine can you provide some feedback please regarding hip and shoulder imaging in particular.
best regards and happy easter to all those celebrating easter. regards David
