[Mristudio-users] How to stop scanner averaging of DTI data?

[Dorian P.]

There is another setting called "average high b". NSA is multplicated with
average high b. For NSA=2 and average high b = 3 the scanner will acquire 6
volumes. You may find more information in the help file of the scanner.
Click the help menu in the upper part and search for these terms.
