Dear all,
I encountered a segmentation problem of my T1-weighted image using caret. After asking
around, the initial diagnosis is that there is quite some inhomogeneity in my image. In
particular, the brightness of my occipital part looks higher than the frontal.
One recommendation is to do a 15-min T1 (currently it's set to 7min). Another
recommendation is to do multiple T1-weighted scans, each about 3 1/2 min and then
average them after registration. My first question is, which might be a better option?
The second question is, if I want to average, say 3 T1-weighted image to create an
averaged T1-weighted image, what is the utility in FSL that would allow me to do so?
Thanks very much
