Abstract
A method for adjusting the display of an MR image includes selecting a subset from a plurality of related MR images, setting at least one of window width and window level display parameters of the selected MR image(s), generating an equation for the parameter as a function of position in the sequence based on the set window width(s) or the window level(s), and then automatically setting window width(s) or window level(s) of other of the plurality of related MR images based on the equation.
