1. A method for generating a presentation of a region-of-interest in an original image for display on a display screen, comprising: establishing a focal region for the region-of-interest at least partially surrounded by a shoulder region; creating a focal region image for the focal region by scaling the original image within the focal region by a focal region magnification; creating a shoulder region image for the shoulder region by scaling the original image within the shoulder region by a shoulder region magnification, the shoulder region magnification being less than the focal region magnification; and, overlaying the focal region image and the shoulder region image on the original image to thereby generate the presentation.
