'Max. SAR per second - Whole Body (Normal, 1st Controlled, 2nd Control)'

| 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 in California? |
Facts and performance do support the indisputable fact that ARMRIT professionals have a greater depth of study and assessment of their technique. ARRT techs are grounded in the modality involving radiation. Cross-training is never the same as dedicated didactic and hands on training with the longest externship vis-a-vis all other modalities...and that is ARMRIT.
California is recognizing ARMRIT. Maybe not at the rate it deserves, especially in hospitals. But it is progressing. ARRT has had a monopoly as a registry. Ultrasound was correct in setting up its own registry. ARMRIT is exercising that right as well; as well it should considering it is a non-ionizing modality to begin with. Several times I have come across ARRT techs who cross-trained for MRI and continually demonstrate "button-pushing", time-cutting habits. I have come across ARRT techs who are employed and doing CT work who are not even certified to do CT!!
The scope of ARRT is wide and the medical system is too privatized to monitor abuses of ARRT techs practicing as non-certified CT or MRI personnel under the umbrella of another certified employee. This is a major loophole that is absolutely doing a great disservice to patients and misrepresenting imaging professionals across the board.
And to those who have stated that ARMRIT is taking away jobs from ARRT.....well, if the qualifications fit the position, then what is the issue with the more qualified, better trained professional being offered the position?
Facilities are recognizing the value of an MRI professional with dedicated training. I was offered a staff technologist position before I even took my boards; the first time in this company's history to employ ARMRIT over ARRT.
During my first 3 months as an employed MRI technologist, I quickly recognized several inefficiencies within many existing protocols used daily at the facility for which I worked. I could not understand how for so long before I started work there, that these inaccurate and unrefined sequences could not have been addressed. Well, an ARRT tech, cross-trained in MRI wrote them.
No disrespect to ARRT. This is not a critique but an observation of the disparity of the domination of ARRT as a registry for modalities it should not have jurisdiction over.
