Patent number: 8977022Abstract: A computed tomography method for determining a volumetric representation of a sample comprising reconstruction initial volume data of the sample from x-ray projections of the sample taken by an x-ray system, determining a part of the reconstructed initial volume data to be updated, and executing an iterative update process configured to generate, using an iterative reconstruction method, updated volume data only for the part of the volume data determined to be updated. Determining the part of the sample volume to be updated comprises individually evaluating every single voxel in the reconstructed initial volume data, based on available quality information for the reconstructed initial volume data, whether or not the voxel fulfils a predetermined condition indicating that an update is required for the voxel, and the iterative update process generates the updated volume data only for the voxels which have been determined that an update is required.Type: GrantFiled: July 9, 2010Date of Patent: March 10, 2015Assignee: GE Sensing & Inspection Technologies GmbHInventors: Eberhard Neuser, Alexander Suppes, Nils Rothe, Michael Hötter, Anja Frost

Publication number: 20140270059Abstract: Embodiments of the systems and methods of this disclosure utilize different positions, or poses, of a target object to collect images that can result in high-resolution volumetric models of the target object. In one embodiment, the object poses define a lateral position and an axial position (also “angular orientation”) of the target object relative to components of an imaging system, e.g., the source of the x-ray beam. The imaging system captures an image of the target object in the object poses. Further processing of the image data that relates to the images generates a volumetric model of the target object at higher resolution, or with fewer artifacts, as compared to similar volumetric models that arise from conventional scanning of these large parts.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Applicant: General Electric CompanyInventors: Alexander Suppes, Eberhard Neuser, Nils Rothe

Patent number: 8515149Abstract: Embodiments of a system and method are described that automate processes to reconstruct models from two-dimensional images. In one embodiment, the systems comprise an apparatus that can acquire a plurality of images of an object and automatedly form a boundary about the object in each of the images. The boundary highlights a portion of the image that will form the basis for the model. The apparatus can also select a primary image from the images, wherein the boundary in the primary image is narrowest relative to an axis that is common to each of the images. In one example, the apparatus can select a secondary image, which is perpendicular to the primary image, and reconstruct the primary image and the second image to generate the model.Type: GrantFiled: August 26, 2011Date of Patent: August 20, 2013Assignee: General Electric CompanyInventors: Nils Rothe, Alexander Suppes, Eberhard Neuser
