A method of generating image alignment data for registration of a pair of medical images selected from a plurality of images derived from different acquisitions (e.g. taken at different times, using different modalities etc) is disclosed. The method comprises determining registration connections for the image pair (e.g. by arranging 1410 images into groups based upon known spatial similarities) and determining 1430,1455 registration weighting values (representative of a registration complexity or computational cost) for each image pair registration connection. The determined weighting values are based at least partly upon intra-image attribute data, such as image size, resolution, contrast/dynamic range, information content etc. Different image pair registration connections yield different weighting values dependent upon the intermediate registration path. The registration path with the lowest weighting value is determined 1480 as the optimal registration path with the lowest degree of registration complexity. The necessary image transformations required to register the image pair via the optimal registration path are determined 1485 to enable image pair alignment data to be generated 1490. A medical imaging system and a computer program product for generating image alignment data for medical images are also disclosed. The method enables generation of reliable image alignment data with reduced computational complexity. |
