Patent number: 9042634Abstract: Aspects of the invention provide a solution for analyzing an object, such as a part of a turbo machine. A planar surface is generated using a curved reformat function based on a surface of a three-dimensional (3D) image of an object. A peel of the 3D image that is adjacent to the surface is determined. Based on the peel, a second planar surface is generated. These two, and/or other similarly generated planar surfaces can be analyzed to determine characteristics of the original object.Type: GrantFiled: January 15, 2013Date of Patent: May 26, 2015Assignee: General Electric CompanyInventors: Sheri George, Haribaskar Govindasamy, Utkarsh Madhav Kulkarni, Pavel Pokutnev, Marko Rosenmueller, Alexander Suppes

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
