1. A method for obtaining at least one corresponding image pair from at least two adjacent sections A and B of a specimen, said method comprising the steps of: a) obtaining a superimage of at least part of section A and a superimage of at least part of section B, wherein a superimage is an image of a section comprising all image fields and an image field is an area of the image to be analysed; b) carrying out an image registration process on the two superimages by establishing correspondence between features of the two related superimages, so as to obtain a mathematical transformation rule, c) identifying an image field within section A; d) using said mathematical transformation rule to identify an area within section B, said area comprising an image field within section B corresponding to said image field within section A, and adding a minimum guard zone to each border of said area in section B; e) obtaining an image of said image field within section A identified in step c) and obtaining an image of said image field within section B identified in step d) and carrying out a second registration process on the two images to obtain a registered corresponding image pair; f) optionally repeating steps c)-e) one or more times to obtain one or more different corresponding image pair(s) of one or more different image fields in the two sections A and B; g) storing a digitized version of said registered corresponding image pair(s) in a non-transitory computer-readable storage medium; and wherein the superimages of step a) are obtained using a lower resolution than the resolution used to obtain the images of step e).
