Noise estimation of T1 brain MR images

[shengyenlin]

Hi,

Thanks for this amazing repo and package.

Recently, I found that I could estimate the standard deviation of the noise from Diffusion-Weighted Imaging (DWI) on your website

But sine I have T1-weighted MR images, I couldn't directly apply noise estimation via this method. Therefore, I would like to ask if there's any specific method that could be applied to T1-weighted MR images? Maybe this question is a little bit basic, but since I'm new to this field, I would be more than grateful that anyone provide some help on this matter.

Thanks in advance :)
