Abstract:
1. A method of computing the transformation which transforms two images ( 10 , 10 ′) of an object, preferably acquired by means of computed tomography or magnetic resonance tomography, one into the other, first the local transformation parameters being successively computed for sub-regions ( 1 , 2 , 3 , 4 , 5 ) of the images and subsequently the overall transformation being computed therefrom, the method of performing successive computation of the local transformation parameters for the sub-regions comprising: a) predetermining or computing the local transformation parameters for at least one first sub-region ( b) forming or selecting at least one sub-region ( c) for each sub-region ( d) repeating the steps b) and c) a number of times until the local transformation parameters have been computed for an adequate distribution of sub-regions across the images.
