fMRI frequency range
Hi,

I am trying to decompose the original fMRI time series into several components with different frequency ranges. I use the MODWT wavelet analysis. To obtain the components' frequencies, I need to know the frequency range of the original fMRI signal. Is it 0-1/TR?

Thanks a lot.

SAR, Magnetic field and exitation frequency
Could you give me the relation between the SAR and the exitation frequency for a given magnetic field ?

Radio frequency exposure
Is there a relationship between SAR and Gauss? A conversion formula? Also, is the EMF exposure reduced by the square or the cube of the distance?

Siemens Skyra 3 T
In MR cardio exams I perform a sequence called trufi-frequencyScout-multi.

This sequence provides several images (from a same slice) each one with a specific frequency.
After this, we choose the better image and use its frequency value as an entry in the cine subsequent sequences.

The question is: Where do I find the place to insert this Value in the Cine sequence?
I travelled all the cine sequence away and could not find.
Anyone can help?

Thanks a lot.
