1. A method for processing slice images, the method comprising: using image sets from at least two imaging directions, wherein an image set is a set of slice images in one imaging direction; automatically correcting misalignment of a first image slice with respect to a second image slice in a target area, wherein the first image slice and the second image slice belong to the same image set in one imaging direction, and wherein said correcting misalignment is carried out by using data from at least one other image set in at least one other imaging direction; defining at least one object of interest from corrected image sets; and forming information indicative of at least one quantitative measure of the at least one object of interest.
