Patent number: 7746340Abstract: Disclosed is a method and apparatus for generating a two dimensional (2D) image of a structure (e.g., an organ) that has at least one pixel corresponding to at least one voxel of a three dimensional (3D) image of the structure. First, the surface of the structure in the 3D image is modeled by a geometrical volume such as an ellipsoid. Next, normal maximum intensity projection (MIP) rays are cast (i.e., projected) for voxels of the geometrical volume. The 2D image is then generated using the rays. The 2D image has at least one pixel that corresponds to at least one voxel of the 3D image.Type: GrantFiled: April 4, 2006Date of Patent: June 29, 2010Assignee: Siemens Medical Solutions USA, Inc.Inventors: Charles Florin, Romain Moreau-Gobard, James P.

Patent number: 7634123Abstract: A method and related system for automatically and efficiently isolating the heart in Computer Tomography (CT) or Magnetic Resonance Imaging cardiac scans is disclosed. The method involves segmenting a heart within a set of volumetric data. In accordance with one aspect of the present invention, the set of volumetric data is processed to determine the minimum value of an energy function having a first term, a second term and a third term. The heart is segmented based on the processing of the set of volumetric data.Type: GrantFiled: March 8, 2006Date of Patent: December 15, 2009Assignee: Siemens Medical Solutions USA, Inc.Inventors: Charles Florin, Romain Moreau-Gobard, Yuri Boykov, Gareth Funka-Lea

Patent number: 7574247Abstract: A novel method is presented for detecting coronary arteries as well as other peripheral vessels of the heart. After finding the location of the myocardium through a segmentation method, such as a graph theoretic segmentation method, the method models the heart with a biaxial ellipsoid. For each point of the ellipsoid, a collection of intensities are computed that are normal to the surface. This collection is then filtered to detect the cardiovascular structures. Ultimately, vessel centerline points are detected using a vessel tracking method, and linked together to form a complete coronary artery tree.Type: GrantFiled: November 8, 2004Date of Patent: August 11, 2009Assignee: Siemens Medical Solutions USA, Inc.Inventors: Romain Moreau-Gobard, Charles Florin

Publication number: 20090024034Abstract: Using a conformal array or an ultrasound probe sequentially positioned at different locations, scans of overlapping regions are performed. A fiber optic sensor or light intensity based sensor determines the relative position of the probe or arrays for each of the scans. This relative position simplifies data correlation by limiting the search and/or is used to determine the relative position of the scans or data. The data may be aligned and combined.Type: ApplicationFiled: July 30, 2008Publication date: January 22, 2009Inventors: ROMAIN MOREAU-GOBARD, Gianluca Paladini
