Hi,
I would like to use SUSAN (instead of 3D Gaussian smoothing) to reduce
noise in my fMRI images whilst preserving the structure. However, I did
not find many published fMRI studies using this kind of approach. Are
there any potential pitfalls concerning the fMRI time series when
volumes are noise reduced? Also, should I use the same brightness
threshold for each volume in the series or calculate it separately per
volume?
Many thanks,
Henry
