| 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

| ARMRIT to ARRT pathway - - - HELP |
Checking in to this forum which is linked from a Google search, "ARRT vs. ARMRIT." Regarding the July 2011 response to my March posting that same year: Have there been any significant changes in the job market in this regard? This post appears to have come from MRI School of Minnesota directly, or someone similar. Understandable, then, that ARMRIT would be defended by someone with such vested interests. There are two points of view that should be distinguished: educators or representatives of ARMRIT who profit whether or not their students finish the course, let alone graduate or find employment in the field. And those earnest ARMRIT certificate bearers who legitimately question the worth of their investment, and want to share their experiences for the benefit of their peers. I am part of the group with this point of view, shared legitimately on this forum. The post continues, suggesting: "It wasn't ARMRIT, buddy--it was YOU they didn't like. Your interview stank!" While not a very clever assertion (and impossible to substantiate) it is nonetheless conceivable that CDI or Regions Hospital, after interviewing me, immediately interviewed and hired another MRI School Of Minnesota graduate. Something unlikely, but what we truly hope for. What the responder to my post and I have in common is the hope that ARMRIT certification becomes recognized, and that this happens soon enough to benefit those of us who are now repaying the loans required to get certified. As for the conversation on this forum (which unfortunately appears to be obscure), each of us has something to do. I will make sure my tie is straight and I've prepared well for the interview. You, in turn might make sure to give us the courtesy of stating your reasons for defending the certifying body (ARMRIT) while casting aspersions on an earnest job-seeker you yourselves certified. Your post seems to defend ARMRIT rather than the hard-working people who earn it.
