Hi xiantong, it depends on how well you match the acquisitions. We have found that if you match them well then for the same field strength you can eliminate most differences, but field strength still results in a small but measurable bias (e.g. 3T vs. 1.5T). Check out Xiao Han's paper on our wiki and also the one by Jorge Jovicich.
