SNR computation on non b=0 shells

I would like to compute SNR on my images. They are neonatal Spinal Cord images acquired with dMRI scheme in order to perform DKI on them.
I managed to quantify SNR on average b=0 images resorting to sct_compute_snr function.
I was wandering whether there is a way to quantify SNR also on other shells different from b=0.
best regards,

Hi @Rosella_Tro,

Yes, you can follow the exact same procedure as described in Snr computation, but select the shell of interest with the flag -vol.

However I would not call it ‘pure thermal SNR’ because the signal intensity is now weighted by the diffusion process. I encourage you to read some of the related literature. E.g.,
