Optimized imaging using non-rigid registration
The extraordinary improvements of modern imaging devices offer access to data with unprecedented information content. However, widely used image processing methodologies fall far short of exploiting the full breadth of information offered by numerous types of scanning probe, optical, and electron microscopies. In many applications, it is necessary to keep measurement intensities below a desired...
متن کاملDiplomarbeit Techniques for Accelerating Intensity - based Rigid Image Registration
One important application of computers in medicine is the merging of various sets of patient data coming from different sources. In the case of image registration, the aim is to determine the translation and rotation by which one data set can be spatially aligned with a second one. Volumetric data (e.g. CT data) can be registered to another volume or to a two-dimensional image (e.g. an X-Ray im...
متن کاملRigid Registration
Rigid registration is the process of identifying the correspondences between two overlapping shapes that were subject to a rigid transformation. Once the correspondences have been established, the underlying rigid transformation can be estimated in the weighted least squares sense with closed form solution. A correspondence is such a pair of points that while they are described in two different...
متن کاملConventional Modalities and Novel, Emerging Imaging Techniques for Musculoskeletal Tumors.
BACKGROUND Imaging of musculoskeletal tumors requires a multimodality approach and includes radiography, computed tomography (CT), and magnetic resonance imaging (MRI). METHODS Topics related to primary bone and soft-tissue tumors are reviewed. The fundamental imaging principles are discussed as well as the applications of emerging imaging modalities. RESULTS MRI is the preferred technique ...
متن کاملRigid registration of different poses of animated shapes
Different poses of 3D models are very often given in different positions and orientations in space. Since most of the computer graphics algorithms do not satisfy geometric invariance, it is very important to bring shapes into a canonical coordinate frame before any processing. In this paper we consider the problem of finding the best alignment between two or more different poses of the same obj...
