Global 3D rigid registration of medical images
Fookes, Clinton B., Williams, John, & Bennamoun, Mohammed (2000) Global 3D rigid registration of medical images. In International Conference on Image Processing, 10-13 September 2000, Vancouver, Canada.
We present in this paper an iterative algorithm for the simultaneous registration of multiple 3D medical images. The proposed algorithmis a point-based registration method and is based on global registration techniques rather than the traditional pair-wise registration methods. Corresponding feature points, known as extremal points, are first automatically extracted from the 3D images and are used as the matching features in the registration process. These extremal points are stable landmarks, as the relative positions of these points are known to be invariant according to 3D rigid transformations. The registration algorithm is based on a novel weighted least squares formulation and it also incorporates 3D noise models on the extracted feature points. Results will be presented for the 3D rigid registration of three successive images of the same patient taken at different periods of time.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
