Mathieu,
these parameters are properties of your image, as CAT12 sees them. There
is no parameter within CAT12 (or any other software solution, for that
matter) that you can change to improve the quality of your original
input images. Based on the quality scores, you may whish to take a
closer look at some images, and make sure that (if you compare groups)
all have a comparable quality.
For this reason, to me, these image quality measures are one of the
hidden gems of CAT12 as I have long harbored a suspicion that many
"group differences" between population with an unequal tendency to move
in the scanner [say, Parkinson or ADHD patients vs. controls] are due to
slightly differing image quality. As you now have an objective quality
control measure, you can check this assumption (and potentially use it
as a covariate later on).
Cheers
Marko
